Bone Scan Myths

What Your DEXA Scan Can Tell You, What It Cannot, and Why Treating a Number Instead of a Human Being Can Backfire

If you have been told you need a bone drug because your DEXA scan says you have osteopenia or osteoporosis, you need to understand something important:

A DEXA scan measures bone mineral density. It does not measure the full biology of bone strength. It does not tell you why your bones are weakening. And it does not always distinguish true pathological bone loss from constitutional differences in body size, genetics, skeletal structure, or other forms of biochemical individuality.

That does not make DEXA worthless. It makes it limited.

The problem is that in the real world, many patients are funneled into treatment discussions that are solely based on the DEXA score. Yet current expert guidance says osteoporosis treatment should be individualized and should account for fracture history, fracture timing and severity, overall risk profile, and more than just the T-score.

The 2024 Bone Health & Osteoporosis Foundation (BHOF) task force specifically states that treatment should be tailored to the individual patient’s risk profile and argues against a one-size-fits-all “bisphosphonate first for everyone” model.

So let’s clear up some of the biggest myths.

Myth #1: A DEXA scan tells me whether my bones are truly strong

Not exactly.

DEXA is a 2-dimensional test that reports areal bone mineral density, but not bone strength.  This is a critical distinction because real bone strength depends on more than mineral quantity. It also depends on trabecular microarchitecture, cortical thickness, porosity, collagen integrity, turnover dynamics, and whether the bone is repairing microscopic damage normally. DEXA tests do not measure all of this.

Bottom line: A DEXA scan provides limited data about bone status, and should not be used as the sole determinant starting treatment with medication.

Myth #2: If my DEXA score is not in the osteoporosis range, my fracture risk is low

A large clinical reality is that many fractures occur in people who do not have osteoporosis by DEXA criteria.  Research has found that the majority of fragility fractures occur in patients with DEXA diagnosed osteopenia, not osteoporosis.

The University of Leeds-linked 2022 paper you mentioned gets at this problem in a very important way. In one study done at the University of Leeds, researchers found that almost half of fragility hip fractures occurred in women with femoral neck T-scores above -1.5, far from the classic osteoporosis cutoff of -2.5.

That means a “better-than-expected” DEXA result can still miss meaningful fracture risk.

Myth #3: DEXA accounts for biochemical individuality

It does not.

One of the biggest flaws in over relying on DEXA is that it tells you nothing about why your BMD is what it is.

Two people can have the same T-score and have completely different biological reasons for getting there. One may have celiac disease or gluten-triggered malabsorption. Another may have hyperparathyroidism. Another may be protein deficient. Another may have low vitamin D, low magnesium, low vitamin K intake, low estrogen, chronic inflammation, thyroid hormone overdosing, steroid exposure, or poor muscle mass. DEXA does not sort that out. It is a density measurement, not a root-cause evaluation.

This is where biochemical individuality matters. Bone is living tissue. It responds to digestion, absorption, inflammation, hormones, genetics, nutrient status, load-bearing exercise, and medication exposure. A printout cannot capture that complexity.

If you treat the number and ignore the biology, you may miss the real reason the bone is weak.

Myth #4: Bone density is mostly the same for people of the same age

No.

Bone mineral density varies substantially from person to person, and genetics play a major role. Reviews and genetic studies report that about 50% to 85% of the variance in BMD is heritable. In other words, inherited biology strongly influences skeletal density and geometry long before a person ever develops age-related bone loss.

This matters clinically because people do not all start from the same baseline. One person may naturally achieve a higher peak bone mass. Another may have a smaller frame and lower areal BMD but still not have the same structural weakness that the scan number seems to imply. Another may carry high-BMD genetic variants. Another may have a skeletal phenotype that makes interpretation more complex.

Age matters. Menopause matters. Inflammation matters. But the same raw DEXA number does not mean exactly the same thing in every human being.

Myth #5: A low DEXA score always means true pathological bone loss

Not always.

This is especially important in smaller-framed individuals.

Because DEXA measures areal density rather than true volumetric density, the result is influenced by bone size. Reviews note that areal BMD is susceptible to body and bone size and may overestimate fracture risk in individuals with a small body frame, who can register lower areal BMD simply because their bones are smaller.

The same concern has been raised by researchers on premenopausal women and other smaller-framed populations. Researchers note that DXA is affected by bone size and that low areal BMD in people with smaller bones raises an important question: are they truly low in volumetric density and bone strength, or are they being mischaracterized by the limitations of the measurement itself?

That means an osteoporotic or near-osteoporotic T-score does not always cleanly separate true disease from variation in frame size, inherited traits, or normal diversity. This is one reason a scan result should never be interpreted in a vacuum.

Myth #6: A high DEXA score always means healthy, fracture-resistant bone

Also false.

High BMD on DXA can be misleading. A major review notes that elevated BMD on routine scanning often reflects degenerative disease, and high values may also result from vascular calcification, spinal osteoarthritis, vertebral fracture changes, or other local artifacts and disorders. That means a “good” number can sometimes be falsely reassuring.

So low numbers can be misleading. High numbers can be misleading. Context matters.

Myth #7: DEXA scans are straightforward and objective, so they rarely mislead

This is wishful thinking.

Mistakes in acquisition, positioning, analysis, and interpretation are not rare. Reviews on clinical DXA use and technical pitfalls describe frequent problems involving patient positioning, scan analysis, artifacts, degenerative change, and reporting errors that can influence diagnosis and treatment decisions.

That means the machine may be precise, but the real-world test is still vulnerable to human and technical error.

Myth #8: If my DEXA says osteoporosis, medication is automatically the right next step

This is where modern medicine often gets it wrong.

Using a DEXA score as the main or only reason to prescribe medications is not good medicine.

Current guidance supports individualized treatment based on the patient’s overall risk profile, including site, number, and severity of prior fractures, plus BMD levels. It specifically says that instead of defaulting to first-line bisphosphonate treatment for all patients, initial therapy should be chosen based on how rapidly fracture risk needs to be reduced and how high the patient’s overall risk is.

In plain English, that means the standard “your scan is low, here is your bone drug” approach is too simplistic.

The problem with prescribing bone drugs from a DEXA-centered model

When medications are prescribed mainly from a scan number, several major problems can happen.

1. The true cause of bone loss may be missed

If the real problem is gluten sensitivity, celiac disease, low protein intake, vitamin D deficiency, magnesium depletion, medication-induced nutrient depletion, thyroid disease, sex hormone loss, chronic inflammation, or poor digestion, a bone drug does not solve the root cause. It may change the scan while leaving the biology uncorrected.

2. Long-term suppression of bone turnover can create new risks

This is where patients are often not adequately informed.

Bone is alive. Healthy bone is constantly being remodeled. Osteoclasts remove old or damaged bone. Osteoblasts lay down new bone. That turnover is not a design flaw. It is part of how bone repairs itself.

Long-term use of powerful antiresorptive drugs, especially bisphosphonates, suppresses remodeling. That can reduce common osteoporotic fracture risk in many patients, but with prolonged use it may also allow microdamage to accumulate and bone tissue to become older, more highly mineralized, and less tough. Reviews of atypical femur fractures describe this mechanism as one involving remodeling suppression, microdamage accumulation, and increased mineralization of older bone tissue.

This is why atypical femoral fractures have become a recognized long-term complication of prolonged bisphosphonate therapy. The paradox is that the scan may look denser while some aspects of tissue quality worsen.

4. Osteonecrosis of the jaw is a real complication, and it is likely undercounted

Medication-related osteonecrosis of the jaw, or MRONJ, is one of the most feared complications of antiresorptive therapy.

Yes, published estimates in osteoporosis-dose patients are often low. The AAOMS 2022 position paper reports low estimated risk ranges for osteoporosis patients using antiresorptives. But that does not mean the true burden is fully captured.

The literature is very clear that under-recognition and under-reporting have been a real issue. In fact, the AAOMS broadened the diagnostic definition in its 2014 update specifically to address evolving clinical observations and concerns about under-reporting. That change expanded the definition beyond visibly exposed bone alone to include bone that can be probed through a fistula.

This is an important distinction because narrow definitions miss cases. Delayed recognition misses cases. Poor awareness among clinicians misses cases. So when you hear that osteonecrosis is “rare,” you should understand that those numbers reflect documented cases, not necessarily every case that occurs in real-world practice. The safest, most evidence-based way to say it is that the true incidence is likely underestimated.

Rare does not mean impossible. And rare does not mean fully counted.

Why long-term bone drug use can increase fracture risk

This is one of the great ironies in osteoporosis care.

Many bone drugs are designed to reduce fractures.  But with long-term bisphosphonate exposure, a different problem can emerge.

When remodeling is suppressed too strongly for too long, bone can become over mineralized and brittle. More precisely, the tissue can become older, microdamage can accumulate, and the normal repair cycle can be impaired. That is why long-term use has been linked to atypical femoral fractures.

So while the average doctor informs the patient that “this drug builds stronger bones,” the deeper truth is more nuanced: some of these drugs can make the bone denser on paper while driving the production of poor quality bone more prone to fracture risk. This is not a reason to panic, but it is a reason to stop pretending that the DEXA score tells the whole story.

What a more intelligent bone evaluation looks like

A smarter approach to bone health asks better questions.

Instead of only asking, “What is the T-score?” the following questions should be asked:

• Have there been prior fractures?
• Is there evidence of silent vertebral compression fractures?
• Are you small-framed, making areal BMD less reliable?
• Are there signs of celiac disease, gluten sensitivity, malabsorption, or chronic gut inflammation?
• What is your overall nutritional status?
• Do you have a chronic inflammatory condition that contributes to bone issues?
• Do you have a abnormal hormone levels? – i.e. Parathyroid, thyroid, estrogen, testosterone, progesterone, DHEA, insulin, cortisol, etc.
• Are you taking steroids, acid blockers, SSRIs, anticonvulsants, thyroid medication, or other drugs that can affect bone?
• Are you building muscle and mechanically loading bone through appropriate exercise?
• Do you have lifestyle factors known to contribute to bone loss?  Smoking, alcohol, sedentary, etc.
• Do you get adequate sleep?
• Do you get adequate sun exposure (main source of vitamin D)?
• Are you overly stressed?

In addition, a more comprehensive laboratory assessment should also be part of your evaluation.  When these tests are used together, a more complete picture is painted, allowing for your doctor to create a more comprehensive bone evaluation, treatment, and monitoring program.

• Osteocalcin (blood)- A vitamin K dependent hormone derived from bone building cells that drives bone mineralization and density.  Elevated levels indicate increased bone breakdown.  (Discontinue use of biotin supplements at least 3 days before measuring.
• Alkaline Phosphatase (blood) – an enzyme made by bone cells.  Low levels may indicate poor bone building.  This marker is linked to insufficient zinc, magnesium, phosphorous, and protein.
• N-telopeptides (NTX – urine) – NTX are small collagen fragments from bone.  Elevated levels can indicate rapid bone breakdown and possible osteoporosis risk.
• Deoxypyridinoline (DPD – urine) – DPD is a peptide responsible for stabilizing type I collagen.  Elevated levels can indicate more rapid bone breakdown.  This peptide is dependent on sufficient vitamin C and copper.
• Intracellular Nutrient Analysis (INA-blood) – The INA test measures vitamins, minerals, amino acids, and other nutrients required for healthy bone formation and maintenance.  In my opinion, this test is the most important and comprehensive test to assess nutritional needs for bone health.

When all of the above is taken together, the doctor and patient are more empowered, more educated, and have a much deeper picture for what is necessary to support bone health.  That is how you move from scan-based medicine to root-cause medicine.

The bottom line

A DEXA scan has value. It can help identify low bone mass. It can help track change over time. It can contribute to fracture-risk assessment.

But it is not a complete bone-strength test. It does not account for biochemical individuality. It does not fully account for genetics. It does not fully correct for body size. It does not reveal the root cause of bone loss. It can miss structural fragility. It can be distorted by artifact. And when it becomes the primary driver of automatic medication prescribing, patients can be exposed to long-term complications while the underlying reason for their bone weakness remains untreated.

The real question is not just, “What does your scan say?”

The real question is, why are your bones weak in the first place, and what is the most intelligent way to restore bone strength without creating new problems?

That is the conversation more patients should be having with their doctors.

FAQ: Bone Scan Myths, DEXA Scan Limitations, and Bone Drug Risks

The post 8 Bone Scan Myths: What DEXA Scans Miss About Osteoporosis, Fracture Risk, and Bone Health appeared first on Gluten Free Society.

GLP-1 drugs are often discussed in terms of weight loss, blood sugar, and appetite control. What gets ignored far too often is the nutritional fallout that can happen when a medication suppresses appetite, slows gastric emptying, and reduces total food intake for months at a time. The available research suggests that the most important nutritional side effects of GLP-1 drugs include inadequate protein intake, loss of lean muscle mass, vitamin D deficiency, B-vitamin problems including thiamine, iron depletion, anemia, and low intake of key minerals like calcium, magnesium, and potassium.

This does not mean every patient on a GLP-1 drug will become deficient. It does mean the risk is clinically important enough that it should not be brushed aside. One 2026 narrative review concluded that GLP-1 receptor agonist therapy is associated with meaningful nutritional deficiencies and that individualized nutritional assessment and lab evaluation may be appropriate, especially in people at higher risk of malnutrition.

Why GLP-1 Drugs Can Create Nutritional Problems

Appetite suppression lowers total nutrient intake

This is the most obvious mechanism. When appetite drops, calorie intake falls. But vitamins, minerals, amino acids, and essential nutrients also come from food. If a patient is eating dramatically less, or skipping meals because they are not hungry, they may also be taking in less protein, less iron, less calcium, less magnesium, and fewer vitamins. Researchers repeatedly identify reduced intake as a major reason nutritional side effects may develop during GLP-1 therapy.

Delayed gastric emptying and gastrointestinal symptoms can worsen diet quality

GLP-1 receptor agonists are also associated with delayed gastric emptying and can cause nausea, vomiting, early fullness, and food aversions. These factors can make it harder for people to tolerate nutrient-dense foods consistently. Appetite suppression, delayed gastric emptying, and altered absorption are all considered plausible contributors to increased micronutrient deficiency risk.

Obesity does not protect against malnutrition

One of the great myths in modern medicine is that excess body fat means nutritional adequacy. It does not.  Many individuals with obesity already have poor diet quality and may already be vulnerable to nutrient gaps before the medication is ever started. GLP-1 therapy can compound that risk.

Protein Deficiency and Muscle Loss on GLP-1 Drugs

One of the most overlooked nutritional side effects of GLP-1 drugs is inadequate protein intake.  Research shows that GLP-1 receptor agonist therapy consistently reduces caloric intake, with frequent inadequacy of protein intake and occasional sarcopenia (age related muscle loss). Additionally many patients fail to reach intake levels needed to preserve lean body mass during weight loss.

That matters because weight loss does not necessarily equate to better health, especially if too much of that loss comes from the muscle.  Muscle is critical for blood sugar regulation, metabolic resilience, strength, mobility, and healthy aging. A patient can celebrate a lower number on the scale while quietly becoming weaker and more nutritionally depleted.  And this nutritional depletion increases the risk of many other chronic inflammatory diseases.

Vitamin Deficiencies Reported With GLP-1 Drugs

Vitamin D deficiency

Vitamin D is the most consistently reported deficiency in the studies you provided. The 2026 narrative review found vitamin D deficiency in 7.5% of patients at 6 months and 13.6% at 12 months.

The 2025 review also reported that in a large retrospective study of 461,328 adults initiating GLP-1 therapy, over 22% developed at least one nutritional deficiency within 12 months, with vitamin D the most common deficiency identified.

Thiamine and other B vitamins

Thiamine (vitamin B1), cobalamin (vitamin B12), and other B vitamins are also effected.  This is especially important clinically because low thiamine and low B12 can affect energy, nerve function, and cognition. Deficiencies in these nutrients are also implicated in cardiovascular disease risk.  The irony being that the purpose of GLP-1 drugs is to reduce cardiovascular disease risk.

Mineral Deficiencies and Anemia Risk With GLP-1 Drugs

The research also points to mineral depletion, not just vitamin issues.  GLP-1 users had 26% to 30% lower ferritin levels. as well as deficiencies in calcium, magnesium, and potassium.

And though many doctors would dismiss these mineral deficits, they are not small problems. Iron is required for oxygen transport and energy. Calcium and magnesium are needed for bone, muscle, nerve function, and cardiovascular regulation. Potassium is essential for muscle contraction, heart rhythm, and fluid balance. If patients are not monitored, these issues can hide behind the headline of “successful weight loss.”

No Standard Nutrition Monitoring Framework Exists for GLP-1 Drugs

Currently no consensus guidelines for micronutrient monitoring in patients receiving GLP-1 receptor agonists are in place. With more and more studies coming out on the nutritional side effects of GLP-1 medications, this is alarming and should serve as a wake up call.

We have a class of drugs powerful enough to suppress appetite, reduce calorie and protein intake, and create clinically relevant nutrient concerns. Yet many patients are prescribed them with little discussion beyond body weight, nausea, constipation, and refill timing. That is not a comprehensive model of care.

Signs Patients and Clinicians Should Not Ignore

A GLP-1 user should not assume that every new symptom is just “part of the adjustment.” Depending on the individual, poor intake and nutrient depletion may contribute to fatigue, weakness, reduced exercise tolerance, hair changes, muscle cramps, lightheadedness, poor recovery, or worsening physical performance.

The bigger point is this: body weight is not a complete measure of health. A patient can lose pounds while also losing lean mass and drifting into nutritional deficiency.

What Should Be Monitored in Patients Taking GLP-1 Drugs?

Even though research is currently limited, a full nutritional assessment is recommended.  All studies to date on GLP-1 medications show nutritional consequences.  Safe than sorry is a good practice when it comes to your health.  That being said, current research supports evaluating the following nutrients at a minimum:

1. Protein intake and lean mass

Preserving muscle should be a priority, not an afterthought.  Protein consumption should be individually tailored to the patients needs.

2. Vitamin D

This is the most consistently reported deficiency in current GLP-1 literature.  A simple 25 OH D blood test can be ordered to monitor vitamin D levels.

3. Thiamine, B12, and other B vitamins

B vitamins regulate energy production and blood sugar.  Monitoring levels can be performed with an Intracellular Nutrient Analysis (INA) test.

4. Iron and ferritin

Iron depletion and anemia risk deserve more attention than they are currently getting.  Ask your doctor for an iron panel with ferritin every 6 months for proper monitoring.

5. Calcium, magnesium, and potassium

These mineral issues can contribute to an array of health problems and should be monitored by your prescribing doctor.

6. Overall diet quality

The research suggests many patients on GLP-1 therapy are eating poorly even before starting the medication, putting them at risk for deficiency even more.

Final Word: Monitor Nutrition, Do Not Just Monitor Weight

If you are using Ozempic, Wegovy, Mounjaro, Zepbound, or another GLP-1 drug, do not make the mistake of thinking the scale tells the whole story.

The scale cannot tell you if your protein intake is too low.
The scale cannot tell you if your ferritin is dropping.
The scale cannot tell you if your vitamin D is deficient.
The scale cannot tell you if your thiamine, magnesium, or calcium status is quietly eroding.

The emerging research is clear enough to justify a more thoughtful approach. GLP-1 drugs may help with appetite and weight reduction, but they may also create clinically meaningful nutritional side effects, especially in patients with poor baseline diet quality, prolonged use, gastrointestinal side effects, or rapid weight loss.

If you are taking a GLP-1 drug focus on the following:

• Have your nutritional status monitored every 6 months using Intracellular Nutrient Analysis (INA – blood test)
• Work with a functional medicine or nutritionally trained doctor or health professional to evaluate your diet quality.
• Ensure that your protein intake is adequate.
• Monitor your body composition to ensure your muscle mass is being preserved.
• Do not settle for weight loss without nutritional oversight.

Monitor, do not guess. Protect your muscle. Protect your nutrient reserves. Protect your long-term health.

High blood pressure is typically presented as a simple salt-and-stress problem, but that is an oversimplification. Blood pressure is heavily influenced by the health of your blood vessels, the degree of inflammation in your body, the integrity of your gut, and whether you are absorbing the nutrients needed to maintain normal vascular tone. 

In some people, gluten can be part of that story. The evidence is strongest in celiac disease, where gluten triggers an autoimmune inflammatory response that damages the small intestine and can spill over into the vascular system. 

That does not mean gluten is the cause of hypertension in every person. It means gluten-related disease may be an overlooked driver in a meaningful subset of people, especially those with gluten induced malabsorption, nutrient deficiencies, autoimmune problems, or inflammatory symptoms.

What the research actually shows

Human studies have reported increased arterial stiffness, higher C-reactive protein, higher erythrocyte sedimentation rate, higher homocysteine, and vascular impairment in people with celiac disease, even when conventional cardiovascular risk factors are not especially elevated. 

A 2024 systematic review and meta-analysis also found that a gluten-free diet was associated with reductions in systolic blood pressure and C-reactive protein, suggesting that in at least some gluten-affected populations, removing gluten may improve vascular risk markers.

A case study published in the Journal of Human Hypertension followed a 49 year old woman with celiac disease whose high blood pressure normalized on the gluten free diet.

A study published in the Journal of Hypertension found that a 90 day gluten free diet led to substantial reductions in systolic and diastolic blood pressure.  

Although researchers have made multiple connections between gluten and hypertension, there is not enough evidence to make the blanket statement that gluten raises blood pressure in everyone. A 2022 Cochrane review concluded that, in the general population, evidence is still very limited and it remains unclear whether gluten intake meaningfully changes blood pressure. 

The short answer

So, can gluten cause high blood pressure? The most accurate answer is yes – gluten may contribute to high blood pressure indirectly by driving inflammation, endothelial dysfunction, hyperhomocysteinemia, and nutrient malabsorption. 

How Gluten May Raise Blood Pressure

Inflammation can damage the blood vessels

Celiac disease is not just a gut issue. It is an immune-mediated inflammatory disease triggered by gluten in genetically susceptible people. Reviews of the literature have linked celiac disease to cardiovascular involvement and have specifically highlighted autoimmunity and inflammation as central mechanisms. That matters because inflammation can reduce nitric oxide availability, impair endothelial function, and increase arterial stiffness, all of which make it harder for blood vessels to relax normally. When vessels lose flexibility and become inflamed, blood pressure can rise.

Why the endothelium matters

The endothelium is the thin inner lining of your blood vessels. It helps regulate dilation, blood flow, clotting, and vascular tone. When the endothelium is injured by inflammation or oxidative stress, blood vessels become less responsive and more rigid. Reviews on homocysteine and hypertension describe endothelial dysfunction as an important mechanism in the development of elevated blood pressure, and celiac-related inflammation has been tied to this same vascular problem.

Celiac disease has been linked to arterial stiffness and vascular impairment

In one study, adults with celiac disease had higher pulse wave velocity, higher inflammatory markers, higher homocysteine, and more evidence of arterial stiffness than healthy controls.

Another study found that adults with celiac disease appeared to be at increased risk of early atherosclerosis, likely driven in part by chronic inflammation, and that these vascular abnormalities improved when gluten was removed and the intestinal lining normalized. 

In plain English, the vessels in untreated or poorly controlled celiac disease may behave as if they are older, stiffer, and more inflamed than they should be.

Homocysteine may be one of the missing links

Homocysteine is an amino acid byproduct that should be recycled efficiently with the help of folate, vitamin B12, and vitamin B6. When those nutrients are low, homocysteine can rise. That matters because elevated homocysteine has been linked to endothelial dysfunction, vascular injury, and hypertension. 

A meta-analysis using Mendelian randomization found evidence supporting a causal link between higher homocysteine levels and hypertension risk, and classic vascular reviews describe hyperhomocysteinemia as a contributor to impaired blood vessel relaxation and increased arterial pressure.

Why this matters in gluten-related disease

In patients with gluten sensitivity and celiac disease, damage to the small intestine can impair absorption of the very nutrients needed to keep homocysteine in check. A well-known case report described a patient with reversible hypertension in the setting of celiac disease, elevated homocysteine, and impaired endothelial function. After a gluten-free diet plus repletion of folate, B6, B12, and iron, the patient’s blood pressure improved and later normalized. A case report is not the same as a randomized trial, but it provides a biologically plausible clinical example of how gluten-related malabsorption could feed into hypertension through homocysteine and vascular dysfunction.

Malabsorption and Nutrient Deficiencies Can Push Blood Pressure in the Wrong Direction

Gluten damage to the gut can reduce absorption of key nutrients

Untreated celiac disease commonly causes deficiency of iron, folate, vitamin B12, vitamin D, zinc, and magnesium, largely because villous damage and brush border injury reduce normal absorption. That is not a fringe observation. It is well described in the medical literature.

Folate, B12, and B6 matter because they regulate homocysteine

When folate, B12, and B6 are low, homocysteine tends to rise. That is relevant to blood pressure because homocysteine is associated with endothelial dysfunction and hypertension. Long-term follow-up data in adults with celiac disease have shown that even people carefully following a gluten-free diet can still have poor vitamin status, which may carry cardiovascular implications through elevated homocysteine.

Magnesium and vitamin D matter because they support vascular function

Magnesium helps regulate vascular tone, smooth muscle relaxation, insulin signaling, and nervous system balance. Vitamin D is also tied to immune regulation and cardiovascular health. Reviews on celiac disease note that magnesium and vitamin D deficiency are common, especially before full intestinal recovery. That means one person may have multiple overlapping hits: immune activation from gluten, damaged intestinal absorption, and lower levels of nutrients needed to maintain normal vessel function.

A gluten-free diet can help, but it is not automatically nutritionally perfect

Here is an important nuance. Going gluten free is necessary for celiac disease, but a gluten-free diet is not automatically nutrient-dense. Reviews have found that gluten-free diets can still be low in B vitamins, iron, calcium, vitamin D, zinc, magnesium, and fiber, particularly when people rely on ultra-processed gluten-free products. So the answer is not just “remove gluten.” The answer is “remove the trigger and rebuild nutritional status.”

Can a Gluten Free Diet Lower Blood Pressure in Non Celiacs?

The strongest human evidence connecting gluten-related disease to blood pressure comes from patients with gluten sensitivity and celiac disease, however; a study of 200 men with uncontrolled high blood pressure found significant reductions in both systolic and diastolic blood pressure when following a gluten free diet. 

The following chart summarizes these findings:

Experimental Research Also Supports a Vascular Effect

A 2024 animal study reported that mice with celiac-like disease induced by gluten exposure showed increased blood pressure and impaired vascular relaxation, along with inflammatory and oxidative stress changes. Animal data do not prove the same effect in humans, but they strengthen the biological plausibility that gluten-triggered immune disease can affect vascular function outside the gut.

Who Should Consider Gluten as a Hidden Blood Pressure Trigger?

You should think about gluten if high blood pressure occurs alongside any of the following

Digestive Symptoms

Chronic bloating, diarrhea, constipation, reflux, abdominal pain, gas, or unexplained weight loss can point to celiac disease or another gut issue affecting absorption. Celiac disease is primarily an intestinal immune-mediated disorder, even though it often has systemic effects.

Nutrient Deficiencies

Iron deficiency, low folate, low B12, low vitamin D, low zinc, or low magnesium should raise suspicion, especially when several show up together or keep recurring. Those deficiencies are commonly described in celiac disease.

Autoimmune Disease or Chronic Inflammation

Celiac disease is autoimmune by nature, and reviews have linked it to broader cardiovascular and inflammatory consequences. If you already have autoimmune disease, unexplained vascular symptoms, or persistent inflammation, gluten should at least be on the differential.

Elevated C-Reactive Protein or Homocysteine

If your homocysteine is high and you also have digestive symptoms, anemia, or other signs of malabsorption, it is worth asking whether gluten-related intestinal damage is part of the reason.

Clinical Perspective From Dr. Osborne

In my clinical experience, numerous patients have achieved significant blood pressure reductions by adhering to the No Grain No Pain diet. This nutritional approach helps decrease chronic inflammation, which in turn facilitates weight loss, enhances mobility, and optimizes nutrient absorption. These collective improvements create a powerful, synergistic effect on overall health.

However, it is important to recognize that a gluten-free lifestyle is not a guaranteed fix for everyone, as hypertension is a multifaceted condition. Because there is no single solution for every scenario, removing gluten may not lower blood pressure in all cases.  

The following chart illustrates who may be the best candidate to consider diet change in relationship to high blood pressure:

What To Do If You Suspect Gluten Is Affecting Your Blood Pressure

Step 1: Do not stop your blood pressure care

Do not use this article as a reason to stop medications or ignore hypertension. High blood pressure can damage the brain, kidneys, heart, and eyes over time. Gluten may be part of the problem for some people, but it is rarely the only variable.

Step 2: Get evaluated for celiac disease before removing gluten

If celiac disease is on the table, testing is usually more accurate before you eliminate gluten. Once gluten is removed, antibodies and biopsy findings may normalize and make diagnosis harder. The evidence linking gluten-related disease to blood pressure is strongest in diagnosed celiac disease, so proper testing matters.

Step 3: Check the terrain

A more complete workup may include nutrient testing, iron studies, folate, B12, vitamin D, magnesium assessment, inflammatory markers, and homocysteine. That is especially reasonable if blood pressure issues are accompanied by fatigue, anemia, neuropathy, brain fog, digestive symptoms, or autoimmune problems. The literature supports a strong overlap between celiac disease, nutrient depletion, and homocysteine-related vascular risk.

Step 4: If gluten is a trigger, remove it completely and rebuild nutrition

For people with celiac disease, the treatment is lifelong strict gluten elimination. Studies suggest that gluten abstinence with mucosal healing can improve vascular abnormalities, and meta-analytic data suggest a modest improvement in systolic blood pressure and C-reactive protein on a gluten-free diet. But the diet must be done well, not just replaced with processed gluten-free junk food.

The Bottom Line

Gluten does not appear to be a universal cause of hypertension in the general population. But in people with celiac disease, and possibly in a broader subgroup with gluten-related inflammatory disease, gluten can contribute to high blood pressure through a multi-step process: immune activation, inflammation, endothelial dysfunction, arterial stiffness, hyperhomocysteinemia, and malabsorption of key nutrients. 

If you have high blood pressure plus digestive symptoms, nutrient deficiencies, autoimmunity, or elevated homocysteine, gluten deserves a closer look. The real question is not whether gluten raises blood pressure in everyone. The real question is whether your body is reacting to gluten in a way that is damaging your gut and your blood vessels at the same time.

Glyphosate is often presented as a simple agricultural tool, a weed killer used to improve crop yields and farm efficiency. But when you step back and examine how glyphosate is actually used in modern agriculture, a very different picture emerges.

Glyphosate is now the most widely used herbicide in the world, sprayed on lawns, parks, school grounds, and most importantly, on many of the crops that make up the foundation of the modern diet. 

In fact, the modern food system has become so dependent on this chemical that policymakers have begun framing its continued production and availability as a matter of national security. 

That reality raises an important question – Glyphosate in food.

If a chemical has become essential to the global food supply, what happens if that same chemical is also contributing to widespread health problems?

Glyphosate in Food – The Farming System is Built On Using It

One of the most revealing developments in the glyphosate debate is how deeply integrated the chemical has become in industrial agriculture.

Today, a large percentage of the crops grown in the United States are genetically engineered to tolerate glyphosate. These crops, particularly corn and soy, were designed so farmers could spray glyphosate directly on the plant without killing it. 

Government subsidies further reinforce this system.

Approximately 90% of farm subsidies go to five major crops:

• Corn
• Soybeans
• Wheat
• Rice
• Cotton

Many of these crops are genetically engineered or heavily treated with glyphosate-based herbicides.  As a result, roughly 80% of row crop farmers depend on glyphosate as part of their agricultural model. 

In other words, glyphosate is not just a weed killer.  It is a foundational pillar of the modern agricultural system.  

Add to this the fact that these crops being sprayed are staples in the diet, leading to wide spread contamination of glyphosate in food.

Why Glyphosate Is Sprayed on Food Right Before Harvest

Most people assume herbicides are used only to control weeds early in the growing season.  But glyphosate is also commonly sprayed on crops right before harvest.

This practice is called pre-harvest desiccation.

Farmers spray glyphosate on crops such as wheat shortly before harvest to kill and dry the plants evenly, which makes harvesting more efficient and economically predictable. 

The problem?  This practice increases the likelihood that glyphosate residues remain on the food that ultimately reaches consumers.

Glyphosate and the Rise of Modern Disease

Researchers studying glyphosate have pointed out a striking pattern: the dramatic rise in glyphosate use has occurred alongside increases in several chronic diseases.

In particular, researchers have observed that the growth in glyphosate application parallels rising rates of conditions such as celiac disease and other modern inflammatory disorders. 

While correlation alone does not prove causation, this relationship has prompted deeper investigation into how glyphosate might affect human biology.

And several potential mechanisms have been proposed.

How Glyphosate May Disrupt Gut Health

One of the most concerning mechanisms involves the gut microbiome.  Glyphosate has antimicrobial properties and appears to preferentially kill beneficial bacteria in the gut.  Especially microbes that help digest complex proteins in foods such as wheat. 

For example, beneficial bacteria like Bifidobacterium and Lactobacillus play a role in breaking down difficult proteins in food.  When glyphosate disrupts these microbes, digestion becomes less efficient, potentially leaving partially digested proteins in the gut that may trigger immune reactions. 

This disruption of the microbiome may help explain why food sensitivities and autoimmune reactions have become increasingly common.

Glyphosate May Interfere With Essential Amino Acids

Glyphosate also affects plants by blocking a metabolic pathway known as the shikimate pathway.

This pathway is responsible for producing three critical amino acids:

• Tryptophan
• Tyrosine
• Phenylalanine 

These amino acids are essential because they serve as precursors to important biological compounds.

For example:

• Tryptophan is required to produce serotonin.
• Tyrosine contributes to thyroid hormone production. 

If glyphosate disrupts this pathway in plants and gut microbes, the nutritional quality of food may decline and key metabolic systems may be affected.

Glyphosate and Mineral Depletion

Another concern is glyphosate’s ability to bind minerals.  Glyphosate can chelate important minerals, meaning it can attach to and bind them in ways that reduce their availability for biological use. 

Minerals such as magnesium, zinc, and iron are essential for:

• enzyme function
• immune regulation
• detoxification pathways

If these minerals are bound and unavailable, nutritional deficiencies may develop even when the diet appears adequate.

Detoxification Pathways May Also Be Affected

Glyphosate may also interfere with detoxification pathways in the body.  Researchers have proposed that glyphosate disrupts enzymes involved in sulfate metabolism and other detoxification processes. 

These systems help the body process toxins and maintain metabolic balance.  If they are impaired, the body may struggle to efficiently eliminate environmental toxins.

A Chemical That Is Now Everywhere

One of the most troubling aspects of glyphosate exposure is how difficult it has become to avoid.

The United States alone accounts for roughly 25% of global glyphosate use, and studies have detected glyphosate even in environmental sources such as rainwater in agricultural regions. 

In other words, glyphosate is no longer confined to farmland.  It has become part of the broader environmental landscape.

The Hard Truth About the Modern Food System

Perhaps the most important takeaway is not simply that glyphosate is widely used.  It is that the modern food system has become structurally dependent on it.  

Because of this widespread adoption, glyphosate in food is becoming a major area of health concern from both consumers and scientists.

From seed design to government subsidies to food processing, entire agricultural systems have been built around glyphosate-compatible crops.   Removing glyphosate overnight could disrupt that system.  But continuing to rely on it puts the health of people at risk for developing cancer. 

Targeted Supplement Support for Glyphosate Detoxification

Because the primary detrimental effects of glyphosate exposure contribute to glycine replacement, increased liver burden, oxidative damage, microbiome disruption, and mineral depletion, I prefer a strategy that focuses on supplementally supporting these areas. 

A simple and focused foundational stack begins with glycine at 3 grams per day. Glycine is one of the major amino acids required to build glutathione, one of the body’s most important detoxification compounds. It also plays a direct role in Phase II detoxification and can help support gut lining repair and tissue recovery. In the context of glyphosate exposure, glycine is especially important because glyphosate’s chemical structure allows it to interfere with normal amino acid biology, making glycine repletion a practical area of support.

Alongside glycine, vitamin C at 2 grams per day helps strengthen antioxidant protection. Detoxification generates oxidative stress, and vitamin C helps buffer that burden while also helping recycle other antioxidants in the body. It supports immune balance, tissue repair, and resilience during periods of increased toxic load.

To directly support liver detoxification pathways, Ultra Liver Detox at 4 capsules per day can serve as a core part of the protocol. The goal here is to nourish the liver’s ability to transform and eliminate toxic compounds more efficiently. When the liver is under stress, detox slows down. Supporting hepatic function is one of the most important priorities in any glyphosate-focused detox strategy.

Because glyphosate may negatively affect the gut microbiome, Biotic Defense at 2 capsules per day is another key part of the stack. A healthy gut is essential for detoxification. The microbiome helps regulate inflammation, influences immune balance, and supports elimination through the digestive tract. When the gut is compromised, toxic burden tends to increase. Restoring microbial balance is an important part of reducing total body stress.

Lastly, Ultra Minerals at 4 capsules per day helps replenish the minerals that are often depleted in people under chronic toxic stress. Glyphosate has been discussed as a compound that may interfere with mineral availability and utilization. If the body lacks adequate minerals, detoxification enzymes, antioxidant systems, and cellular repair mechanisms cannot function optimally. Replacing those reserves is a critical step.

Put together, this stack is designed to support five key areas at once: glutathione production, antioxidant defense, liver detoxification, gut microbial balance, and mineral repletion. That is the kind of foundation I like to see in place when helping someone reduce toxic burden.

The Dr. Osborne Supplement Stack for Supporting Glyphosate Detox
Glycine: 3 grams per day
Detox C: 2 grams per day
Ultra Liver Detox: 4 capsules per day
Biotic Defense: 2 capsules per day
Ultra Minerals: 4 capsules per day

This type of protocol works best when combined with lowering your exposure.  Research is very clear that eating organically dramatically reduces toxic accumulation.  As part of your detox strategy, you should prioritize cleaner food and water, proper hydration, regular bowel movements, sweating, movement, and a nutrient-dense anti-inflammatory diet. Supplements should support the detox process, not substitute for the foundations that make detox possible.

Conclusion

Glyphosate sits at the center of a complex intersection between agriculture, economics, and human health.  It helps sustain the efficiency of the current Big Government/Big Agra industrial farming complex.

But the same chemical may also be interfering with gut health, nutrient availability, detoxification pathways, and the biological integrity of the foods we eat.

The uncomfortable reality is that modern agriculture has engineered itself into a system where removing glyphosate would be disruptive to mass scale food production, while continuing to rely on it is disruptive to the health of Americans.  Understanding that tension is the first step toward changing it.

Frequently Asked Questions About Glyphosate

What is glyphosate?

Glyphosate is a widely used herbicide designed to kill weeds and unwanted plant growth. It is the active ingredient most people associate with Roundup, although not every herbicide product contains glyphosate and not every glyphosate product is branded as Roundup.

How does glyphosate get into food?

Glyphosate can get into food when it is sprayed on crops during growth or used shortly before harvest as a drying agent on certain crops. Residues may remain on or in foods made from those crops, especially in products derived from conventionally grown grains, legumes, and some processed foods.

Why is glyphosate sprayed before harvest?

In some farming systems, glyphosate is used before harvest to help dry crops down more evenly and speed harvesting. This practice is often referred to as pre-harvest desiccation. It can be one reason consumers become concerned about glyphosate residues in food.

What foods are most likely to contain glyphosate residues?

Foods made from conventionally grown wheat, oats, corn, soy, legumes, and certain processed grain-based products have been tested and shown to be the most contaminated.

Is glyphosate the same thing as Roundup?

Not exactly. Glyphosate is a chemical active ingredient. Roundup is a brand name that has included glyphosate-based formulations. People often use the two terms interchangeably, but they are not technically identical.

Why is glyphosate so controversial?

Glyphosate is controversial because it sits at the center of an ongoing debate involving agriculture, food production, toxicology, public health, cancer risk, environmental exposure, and regulation. Some agencies and researchers have taken different positions on its long-term safety, which has fueled public confusion and legal battles.

What is the difference between glyphosate and glyphosate-based herbicides?

Glyphosate is the active ingredient. A glyphosate-based herbicide is the full commercial product, which may also contain other ingredients such as surfactants or adjuvants. Some researchers argue that the additional ingredients may be detrimental to health as well. 

Does glyphosate only affect farmers?

No. Farmers and agricultural workers may face higher direct exposure, but consumers can also encounter glyphosate indirectly through food, water, and environmental contamination. The degree and relevance of that exposure depends on many factors, including diet and location.

Does eating organic reduce glyphosate exposure?

Choosing organic food may help reduce glyphosate exposure because certified organic farming restricts the use of glyphosate. That said, organic is not the only factor that matters. Food sourcing, total diet pattern, water quality, and the amount of ultra-processed food in the diet can all play a role.

Can glyphosate affect the gut microbiome?

This is an area of ongoing debate and research. Some scientists have raised concerns that glyphosate may influence microbial balance because it was designed to disrupt a biological pathway found in plants and some microbes. More research is still needed to clarify how this may translate to real-world human health outcomes.

Can glyphosate contribute to nutrient problems?

Some researchers and clinicians have proposed that glyphosate may interact with minerals, gut function, or food quality in ways that could affect nutrient status. This is still an area that requires careful interpretation. It is best presented as a possible mechanism under investigation, not as a settled fact.

Why is glyphosate in the news right now?

Glyphosate remains in the news because of ongoing lawsuits, regulatory debate, food-supply concerns, and public-health questions. That combination keeps it relevant not just as a farming issue, but as a consumer, legal, and policy issue as well.

How can I reduce my glyphosate exposure?

A practical strategy starts with eating more whole foods and fewer ultra-processed foods, prioritizing organic versions of high-risk crops when possible, washing produce, diversifying food sources, paying attention to water quality, and reducing dependence on grain-heavy packaged products. 

Should I panic if I have been exposed to glyphosate?

No. Panic is not productive. A better approach is to become informed, reduce avoidable sources of exposure, and focus on a stronger nutritional foundation, cleaner food choices, and lifestyle habits that support resilience and detoxification.

The post Glyphosate Exposed: How a Weed Killer Became Embedded in the Modern Food System appeared first on Gluten Free Society.

You can eat “clean,” take a multivitamin, and still be running on empty.

Why? Because deficiencies are rarely about willpower. They are about physiology. Absorption, medication side effects, stress chemistry, ultra-processed foods, immune reactions to grains, and toxin load can all drain your nutrient reserves faster than you can refill them.

Below are the 6 biggest drivers I see, plus what to do about each one.  What causes vitamin & mineral deficiencies?  Let’s Dive in.

The “Hidden Truth” About Deficiencies

Your body is not a simple input-output machine.  Nutrients only count if you can:

• Digest them
• Absorb them
• Transport them
• Activate them
• Use them inside cells

When any part of that pipeline breaks, deficiencies show up even with “normal labs” and “good diets.”

#1: Broken GI Tract Absorption

If your gut is inflamed, leaky, low in stomach acid, or dysbiotic, you can eat well and still develop deficiencies.

Here’s a simple breakdown of your digestive tract and other factors needed for healthy absorption:

Digestion Starts in the Mouth

Physical breakdown begins with chewing.  Chemical breakdown happens through digestive enzyme secretions in your saliva.  If you have oral health issues, these problems can make it harder to extract nutrients from your food.

Stomach Acid

Stomach acid helps liberate minerals and supports proper digestion and breakdown of proteins. When acid is low, digestion slows and absorption often suffers. This is one reason acid-reducing drugs can backfire long-term (more on that in section #2).

Liver and Bile Flow

Your liver produces bile.  Bile helps emulsify fats so you can absorb fat-soluble vitamins A, D, E, and K. When bile flow is impaired (cholestasis and other bile-related issues), fat absorption drops and fat-soluble vitamin deficiency risk rises.

Pancreatic enzymes

Your pancreas provides enzymes that digest fat and protein. When enzyme output is low (exocrine pancreatic insufficiency, chronic pancreatitis, post-surgery changes), nutrient malabsorption becomes predictable. In chronic pancreatitis and pancreatic insufficiency, deficiencies of fat-soluble vitamins are common, and protein digestion issues can impair B12 handling.

Gut Inflammation & Malabsorption Conditions

Many inflammatory GI disorders that impair fat absorption can reduce fat-soluble vitamin uptake.  Inflammation to the GI tract can also contribute to water soluble vitamin and mineral deficiencies.  Common inflammatory conditions include celiac disease, Crohn’s, ulcerative colitis, and pancreatitis.

Action steps

If you have bloating, greasy stools, floating stools, unexplained weight loss, chronic reflux, or chronic diarrhea, do not assume it is “normal.”

Talk with your clinician about evaluating:

• Pancreatic function (especially if stools are oily or you have upper abdominal symptoms)
• Bile flow and liver markers
• Celiac and gluten-related genetic markers or antibody tests.

Read the following comprehensive breakdown on digestion for more detailed information.

#2: Medications Drain Nutrients

This is one of the most under-discussed causes of nutrient depletion in modern medicine.

Proton pump inhibitors (PPIs) and acid reducers

Long term PPI use has been associated with increased risk of deficiencies involving protein, vitamin B12, iron, calcium, magnesium, zinc and vitamin C metabolism.

That matters because low acid can reduce the breakdown and release of nutrients from food.  These nutrient deficits can in turn effect the functionality of the gut, creating a vicious circle.

Metformin

Metformin, a diabetic medication, is most well known for causing vitamin B12 deficiency  Additionally, it has also been linked to folate and CoQ10 deficiency.

If you are on metformin and you start to develop tingling, numbness, burning feet, fatigue, or anemia, you should ask you doctor to immediately check your B12, folate, and CoQ10 levels, as a deficiency of these key nutrients are known to cause this symptom cluster.

Statins

Statins have been shown to block CoQ10 production in clinical trials, with multiple analyses reporting significant reductions.

Why this matters:  lowered CoQ10 is linked to nerve damage, muscle pain, fatigue, weakness, and cramping.  All of these are factors that can lead to exercise avoidance, but also more serious complications.  If you are taking statins, strongly consider both monitoring your levels as well as supplementing with CoQ10.

Blood Pressure Medications

Diuretics can increase urinary loss of both vitamins and minerals.  Nutrients known to be commonly depleted include, vitamin B1, B6, B9, magnesium, calcium, potassium, zinc, and CoQ10.

The irony is that deficiencies of these nutrients can elevate blood pressure and heart disease risk.  If you are taking blood pressure medicines, make sure to ask your doctor to monitor your levels, and supplement accordingly.

Steroids (glucocorticoids)

Steroids commonly prescribed to reduce pain and inflammation can reduce intestinal calcium absorption and increase urinary calcium loss, contributing to bone loss risk over time.  Additionally, these medications can deplete vitamin D, magnesium, potassium, zinc, selenium, vitamin C, vitamin A, folate, B6 and B12.

NSAIDs (aspirin, ibuprofen, naproxen, etc.)

Non steroidal anti-inflammatories (NSAID’s) can cause damage to the stomach and intestinal lining.  This is often associated with occult bleeding that contributes to iron loss and deficiency.  In addition, NSAIDS can deplete folate and vitamin C.

Tylenol (acetaminophen)

Acetaminophen is metabolized into a toxic intermediate (NAPQI) that is detoxified by glutathione.  This process can deplete glutathione stores, especially in overdose but also as a core part of the pathway.

Hospitals give N-Acetyl Cysteine, a direct precursor that increases glutathione to patients with acetaminophen overdose.

SSRIs and electrolyte depletion

SSRIs are strongly associated with hyponatremia (low sodium) Low sodium can cause headaches, nausea, muscle aches, cramps, and fatigue.  In addition, these medicine have been associated with lower vitamin D and calcium, increasing the risk for bone loss.

Hormones (HRT and birth control)

Oral contraceptive have been linked to many nutritional deficiencies, including CoQ10, B vitamins and minerals like magnesium, selenium, copper, and zinc.

With an increased popularity of women taking estrogen long term, there is a greater concern for the development of deficiencies that can contribute to health issues.  If you are taking estrogen or HRT, ask your doctor for an intracellular nutrient analysis (INA).

The diagram below illustrates additional drug induced nutritional deficiencies:

Bottom line:

• If you are taking prescription medications, Test, Don’t Guess when it comes to preventing nutritional problems.
• Ask your clinician: “Which nutrients does this medication deplete, and what should we monitor?”
• Do not stack supplements blindly. Identify your deficiencies first.

Testing: Why I like Intracellular Nutrient Analysis (INA)

Standard blood tests can be helpful, but they do not always reflect functional nutrient status inside cells.

Intracellular Nutrient Analysis (INA) is designed to assess functional deficiencies at a cellular level where the nutrients work.

In plain terms:

• Serum can look “normal” while tissues are struggling.
• INA identifies whether or not your cells on functioning properly based in their nutrient adequacy.

This is especially worth considering if you have symptoms, chronic inflammation, gut issues, toxin exposure, or long-term medication use.

#3: Chronic Stress

Stress is not just a feeling. It is a biochemical state.  Chronic stress burns through your nutritional reserve tank.

When stress stays “on,” your body shifts into a fight or flight state leading to:

• higher demand for energy metabolism
• higher turnover of neurotransmitters
• higher oxidative stress burden
• higher stress hormone synthesis demands

This shift in biochemistry increases the body’s demand for vitamins and minerals.  Subsequently, chronic stress has been linked to deficiencies in zinc, calcium, magnesium, iron, vitamin C, and B vitamins.

Many people turn to heavy caffeine use to overcome stress induced fatigue and a vicious cycle ensues.  When done in excess, caffeine intake (more than 400 mg/day) has been shown to deplete nutrients.   In addition, high stress pushes people toward convenient ultra processed food choices devoid of adequate nutrients.

Action steps

If you are burned out and wired, treat stress like a medical risk factor.  Start with the basics daily choices that can have the biggest impact:

• Sleep timing and consistency
• Exercise to tolerance only
• Hydration and electrolytes
• Eat real food (Avoid processed)
• Process your emotions and give yourself forgiveness and grace
• Consider taking a high potency multi-vitamin/mineral.

#4: Sugar, Soda, Alcohol, & Ultra-Processed Foods (overfed, undernourished)

Consumption of empty calories, alcohol, chemical preservatives, and pesticides create a nutritional deficiency time bomb.  This behavioral pattern has been the standard norm for the past several decades.  The outcome?  A nation of malnourished, disease laden people turning to medications as a means to manage the symptoms largely caused by poor dietary decisions.

Ultra-processed foods (UPFs) displace micronutrients and are linked to chronic diseases, UPFs often deliver high amounts of:

• Refined starch
• Refined oils
• Added sugar
• Synthetic preservatives and flavors
• Processed food gums and artificial sweeteners
• Microplastics
• Pesticides
• Toxic Metals
• Low micronutrient density

Alcohol: a proven deficiency accelerator

Chronic alcohol intake is has long been linked to severe nutritional problems.  Over the past many years, there has been an industry driven social push to normalize alcohol as safe and non problematic.  Take for example the fact that wine has been recommended by cardiologists as “heart healthy”, despite the fact that it is a known toxin that causes vitamin and mineral deficiencies.

Action steps

Replace liquid calories first. Remove soda and reduce alcohol.  Build your plate around healthy grain free ingredients:

• Nutrient dense, organic whole foods
• Grass fed/finished meats
• Free range, organic chicken and eggs
• Wild caught fish
• Organic fruits, vegetables, and nuts.

If you rely on protein powders or packaged “health foods,” choose brands that provide transparent contaminant testing where possible.

#5: Gluten & Grain Consumption

This is not about trendy dieting. This is about immune biology and gut integrity.  The evidence for grains driving nutritional deficiencies is clear.  I wrote extensively about this in my book No Grain No Pain.  

When the gut lining is damaged, malabsorption becomes the norm.  Autoimmune inflammation from grains drives up stress hormones, causes tissue damage, and drives demand on nutrients needed for healing and repair.  The cycle is known as Grainflammation.

If you want clarity about whether a gluten free diet is right for you, consider taking our gluten quiz, having genetic testing performed, or visiting with a doctor who is gluten literate.  You can learn more about how gluten causes vitamin and mineral deficiencies here.

#6: Food Chemicals & Environmental Toxins

Detox is not a fad word. Your body has dedicated pathways to help you process and eliminate chemicals and environmental toxins.

Those pathways rely on vitamins and minerals for proper function.  Processed foods are heavily contaminated with chemical additives, emulsifiers, and preservatives. The presence of these compounds drives up demand for nutrients in order to help the body process and eliminate them.

When environmental toxic exposures from pesticides, herbicides, microplastics, toxic metals, toxic molds, mycotoxins, and medications are added to this burden, detox pathways can become overwhelmed, and nutritional deficiencies are often the consequence.

Detox Requires Nutrients

Detoxification is a complex, two phase process occurring primarily in the liver.  The goal is to transform fat soluble toxins into water soluble substances that can be safely eliminated from the body through urine, sweat, and the bowels.

Phase I detoxification relies on a family of enzymes known as cytochrome P450 (CYP450). During this phase, CYP450 enzymes use chemical reactions to break the toxin down into something smaller.  This first step leads to the formation of free radicals.  If the body lacks adequate nutrient antioxidant defenses, these free radicals can create to other cells.

The main nutrients required for Phase I include:

• B-vitamins (B2, 3, 6, 9, and 12)
• Magnesium & Zinc
• Glutathione
• Antioxidants – vitamin E, C, and selenium

Phase II detoxification acts to safely package and neutralize the reactive compounds generated during Phase I. In this stage, enzymes attach (or conjugate) a water-soluble molecule to the toxin. This conjugation effectively “wraps” the toxin, neutralizing its harmful effects and transforming it into a water-soluble compound that can be safely excreted form the body through the GI tract, urine, or sweat.

The main nutrients required for Phase II include:

• Vitamins – B1, B5, folate, B6, B12, and Vitamin C
• Minerals – Magnesium, molybdenum, selenium, sulfur
• Amino Acids – Methionine, Glycine, Taurine, Glutamine, Cysteine
• Glutathione
• Betaine
• Water

Bottom Line:

The more toxins your are exposed to, the more nutrients your liver needs to process and eliminate them.

#7: Bonus – What Else Causes Vitamin and Mineral Deficiencies?

Lack of nutrient intake

Poor soil quality has become increasingly depleted due to modern farming practices. This means that we could eat the same food today as our grandparents did a few decades ago and we get fewer nutrients.

Phases of Life

Certain phases of life demand a higher nutrient intake. If you don’t meet that need, you can easily become depleted. Some examples include the following:

• Growth spurts: Baby, children, and adolescents are growing quickly and they require more nutrients to accommodate their growth spurts. For example, adolescents are more likely to develop zinc deficiency as their body is growing because the body requires more zinc during this time.
• Pregnancy: Pregnancy is among the most nutritionally demanding phases of life, as the nutrients a pregnant woman consumes must cover the needs of herself as well as her growing baby.
• Breastfeeding: Like pregnancy, breastfeeding involves a woman feeding and nourishing both herself and her baby.
• Increased or intense exercise: Exercise has wonderful benefits for the body but is also a muscular trauma that requires nutrients for healing and repair, and regrowth of the tissue. This results in a higher demand for nutrients in order to heal and repair the damage induced by the exercise.
• Trauma: Similar to exercise, trauma in the form of a sprain, tissue damage, a broken bone, injury, or other traumatic event requires additional nutrients for healing and repair.
• Chronic inflammatory disease: Chronic diseases like diabetes, autoimmune disease, and celiac disease cause increased inflammation in the body, which results in heightened nutrient needs to help manage the inflammation.

Increased loss of nutrients

Certain conditions and situations cause the body to lose nutrients at a faster rate, making a deficiency more likely. Such conditions include the following:

• Kidney disease: malnutrition in those with chronic kidney disease results from a combination of a number of issues, including decreased appetite and nutrient intake, hormonal derangements, metabolic imbalances, inflammation, increased catabolism, and dialysis related abnormalities.
• Burns: nutrients can be lost through a burn
  Aggressive skin inflammation: psoriasis or eczema lose proteins and nutrients more aggressively)
• Surgical procedures: Certain surgical procedures performed on various components of the digestive system can influence nutrient absorption. For example, gastric bypass affects the stomach, cholecystectomy (removal of the gallbladder) impacts bile secretion and fat absorption, and intestinal resection results in less area for nutrients to be absorbed.

How to Reduce Your Risk of Developing Nutritional Deficiencies

Diet and lifestyle choices can have a profound impact on your nutritional status.  Consider the following to preserve and optimize your body’s nutritional bank account.

Make Good Choices

• Eat whole, nutrient dense, organic foods with minimal to no processing
• Use safe, non toxic cookware
• Filter your water
• Filter your air
• Use natural hygiene and self care products
• Use natural house hold cleaning products
• Get regular sunshine exposure
• Go outside and get exposure to nature.  Flowers, trees, animals, etc
• Limit your screen time.  Excessive blue light exposure and EMF can also drive nutritional deficits
• Get enough sleep
• Exercise and move your body
• Manage your relationships and set clear boundaries to reduce stress
• Have fun – Don’t forget that the pursuit of improving your health to extreme degrees can create stress.  Make sure you are living a life of purpose and fulfillment.

Test, Don’t Guess

If you are making great choices, but still struggling in your health, consider having your nutritional status checked.  Have an intracellular nutrient analysis (INA) performed.  Customize your food choices to your deficits.  Consider supplementation.  If this feels overwhelming, work with an experienced nutritional expert.

FAQ: What Causes Vitamin & Mineral Deficiencies?

The post What Causes Vitamin & Mineral Deficiencies appeared first on Gluten Free Society.

The post Dr. Osborne’s Natural Pain Remedies appeared first on Gluten Free Society.

What Is Inositol?  

In simple terms, inositol is a naturally occurring type of sugar that your body produces and uses to keep your cells functioning correctly.  

While it was historically referred to as Vitamin B8, it is not technically a vitamin because your body can make it on its own (primarily in the kidneys). It is a carbohydrate found abundantly in the brain and other tissues.

There are nine different “forms” (isomers) of inositol, but when you hear people talking about “inositol benefits” or reading research papers, they are almost exclusively referring to myo-inositol. This is the most stable and abundant form in the human body.

Inositol acts as a structural component of cell membranes and influences the action of insulin and neurotransmitters like serotonin and dopamine.

Inositol is not a drug.  Like a vitamin, it behaves as a functional facilitator. It doesn’t force your body to do something; it helps your body’s internal messaging system work the way it was designed to.

How Inositol Works (The “Doorbell” Analogy)

To understand why inositol helps with such different conditions, you have to understand cell signaling.

The easiest way to visualize this is the Doorbell Analogy:

1. The Caller (Hormone): Imagine insulin is a person ringing your front doorbell. It wants to deliver a package (glucose/sugar) into your house (the cell).
2. The Door (Receptor): The doorbell rings, but the door is locked.
3. The Key (Inositol): Inositol acts as the “secondary messenger.” When the doorbell rings, inositol is the person inside the house who hears it, gets up, and unlocks the door to let the insulin do its job.

The Problem:  In conditions like insulin resistance or PCOS, the “caller” (insulin) keeps ringing the bell, but nobody answers. The body responds by sending more callers (producing more insulin), leading to high blood sugar, inflammation, and hormonal chaos.

The Solution: Supplementing with inositol ensures there is someone “inside the house” to answer the door. By improving this signaling pathway, inositol helps the body become more sensitive to insulin, which can have a cascading positive effect on sex hormones, egg quality, and metabolic health.

Evidence-Based Benefits

Not all benefits are created equal. Below, we rank the uses of inositol based on the strength of current scientific evidence.

Polycystic Ovary Syndrome (PCOS)

Strength of Evidence: High

This is the area where inositol shines brightest. PCOS is a complex hormonal condition often driven by insulin resistance.  Because inositol improves insulin sensitivity, it targets one of the root causes of PCOS rather than just masking symptoms.

Research suggests inositol supplementation may help:

• Restore Ovulation: Multiple studies have shown that myo-inositol can help restore regular menstrual cycles and spontaneous ovulation in women with PCOS [Source: Gynecological Endocrinology].
• Lower Androgens: It has been associated with reduced levels of testosterone and other androgens, which drive symptoms like acne and hirsutism (excess hair growth).
• Improve Egg Quality: For those undergoing fertility treatments, inositol is often used to improve oocyte (egg) quality.

Insulin Resistance and Metabolic Syndrome

Strength of Evidence: Moderate to High

You do not need to have PCOS to benefit from inositol’s metabolic effects. Metabolic syndrome is a cluster of conditions (high blood pressure, high blood sugar, excess body fat around the waist) that increase the risk of heart disease and diabetes.

A systematic review published in Molecules highlighted that myo-inositol supplementation is effective in lowering fasting blood glucose and improving HOMA-IR (a marker of insulin resistance) 

Furthermore, it may help improve lipid profiles by lowering triglycerides and LDL (“bad”) cholesterol, though results can vary based on the individual’s starting health markers.

Panic Disorder and Anxiety

Strength of Evidence: Moderate 

While often touted as a general “anti-anxiety” supplement, the strongest clinical evidence is specifically for panic disorder.

Inositol affects neurotransmitters like serotonin and GABA. A famous double-blind, crossover study published in the Journal of Clinical Psychopharmacology compared inositol to fluvoxamine (a common antidepressant). The study found that 18 grams (a very high dose) of inositol per day significantly reduced the frequency of panic attacks, with fewer side effects than the medication.

Important Note: The doses used for mental health in studies (12g–18g) are much higher than doses used for PCOS (2g–4g). Low doses may not have the same effect on the brain.  If high doses seem unappealing, you might consider adopting a gluten free diet change.  The connection between gluten and anxiety is strong.

Gestational Diabetes (GDM)

Strength of Evidence: Promising but Mixed

Some research indicates that taking myo-inositol during pregnancy may reduce the risk of developing gestational diabetes, particularly in women who are overweight or have a family history of diabetes. A 2015 Cochrane review found that myo-inositol was associated with a reduction in GDM rates.

However, guidelines are still evolving, and you should always work with your OB-GYN before adding supplements during pregnancy.

Summary of Research Based Inositol Benefits 

How to Use Inositol (Dosage & Timing)

Because inositol is a water-soluble nutrient, it is generally considered safe and non-toxic, but getting the dosage right is key to seeing results.

Typical Dosages in Studies

• For PCOS & Metabolic Health: The “gold standard” dose in most successful studies is 2,000 mg (2 grams) taken twice daily, for a total of 4,000 mg per day.
• For Fertility Support: Usually 4,000 mg daily (taken in two divided doses) often taken for 3 months prior to conception or IVF retrieval.
• For Panic/Mental Health: Studies have utilized 12,000 mg to 18,000 mg (12–18 grams) daily. This requires a powder form, as swallowing that many capsules is impractical.

How to Start (“Start Low, Go Slow”)

If you take a full 4-gram or 12-gram dose on day one, you will likely experience gas, bloating, or diarrhea. Your body needs time to adjust.

• Week 1: Start with 1,000 mg (1g) with breakfast.
• Week 2: Add a second 1,000 mg dose with dinner.
• Week 3: Gradually increase to the target dose (e.g., 2g twice daily).

Timing and Evaluation

• When to take it: Inositol is usually taken with meals, but it can be taken on an empty stomach as well.
• How long to wait: Supplements are not immediate. For cycle regulation and metabolic changes, commit to a trial of at least 3 to 6 months.

Inositol Usage Summary 

Side Effects, Safety, and Who Should Avoid It

One of the reasons inositol is so popular is its safety profile. Since it is a substance your body naturally makes, allergic reactions are extremely rare. However, side effects are possible.

Common Side Effects (Usually GI-related):

• Nausea
• Gas and bloating
• Diarrhea / loose stools

Dosing Tip: Side effects are almost always dose-dependent. Reducing your dose for a few days usually resolves the issue.

Who Should Use Caution?

• Bipolar Disorder: There are isolated case reports suggesting that high-dose inositol might trigger a manic episode in people with bipolar disorder. If you have bipolar disorder, only use inositol under strict psychiatric supervision.
• Diabetics on Medication: Because inositol lowers blood sugar, taking it alongside insulin or drugs like Metformin or Glyburide could theoretically cause hypoglycemia (blood sugar dropping too low). Monitor your levels closely.
• Pregnancy & Breastfeeding: While studies suggest safety and benefit for gestational diabetes, you should never start a new supplement during pregnancy without doctor approval.

Food Sources vs. Supplements

You might be wondering, “Can’t I just eat more fruit?” Inositol is found naturally in many foods. Top grain free sources include:

• Cantaloupe and citrus fruits (except lemons/limes).
• Beans and legumes (great northern beans, lima beans).
• Nuts (almonds and walnuts).

The Challenge With Food Based Inositol: The average diet provides about 1 gram (1,000 mg) of inositol per day. However, the therapeutic doses used in studies for PCOS and anxiety are 4 to 18 grams.  

While eating an inositol-rich diet is healthy, it is virtually impossible to eat enough cantaloupe to reach the levels shown to help with insulin resistance or panic attacks. This is why supplementation is usually required for therapeutic effects.

Who Is Most Likely to Benefit? (A Checklist)

Inositol might be a good fit for your regimen if you check one or more of these boxes:

• [ ] You have been diagnosed with PCOS.
• [ ] You have irregular periods or do not ovulate regularly.
• [ ] You struggle with sugar cravings and “hangry” crashes (signs of blood sugar instability).
• [ ] You have elevated fasting insulin or glucose levels.
• [ ] You are looking for a non-pharmaceutical support for panic attacks (under doctor supervision).
• [ ] You are trying to conceive and want to support egg quality.

Common Mistakes to Avoid

To get the most out of inositol, avoid these common pitfalls:

• Expecting weight loss immediately: Inositol is not a fat burner. It supports proper glucose metabolism, which can lead to weight loss over time, but usually only when combined with dietary changes.
• Quitting too soon: Many women stop after 4 weeks because they haven’t seen a change in their cycle. Hormonal shifts take time.  Give it at least 90 days.
• Using the wrong form: Stick to myo-inositol (or products simply labeled “inositol,” which is usually myo-inositol).
• Ignoring lifestyle: Inositol helps open the cellular door to insulin, but if you are consuming massive amounts of refined sugar, you are still flooding the system. It works best as a partner to a whole-foods diet.

Key Takeaways

• Myo-inositol is a natural compound that helps your body handle insulin and brain chemicals more effectively.
• It is one of the most researched natural supplements for PCOS, showing the ability to improve ovulation and metabolic markers.
• For metabolic health, a standard dose is 4 grams daily (2g twice a day).
• For panic disorder, much higher doses (up to 18 grams) are required to match clinical trials.It is generally safe and well-tolerated, with mild stomach upset being the main side effect.
• It is not a quick fix; commit to a 3-month trial to truly evaluate its benefits for your hormones and mood.

What Are the Most Effective Supplements for Lowering Blood Sugar?

If you have been diagnosed with prediabetes, type 2 diabetes, or metabolic syndrome, you are likely being told that medication is your only path forward. You might be taking metformin or even injecting insulin, yet your numbers are still creeping up.

You are looking for a better way. You want to know if there are natural tools – vitamins, minerals, and botanicals that can help you regain control.

The answer is yes, but we need to clear the air first: Supplements are not magic pills. You cannot out-supplement a bad diet. If you are still eating grains, ultra processed foods, processed sugars, and inflammatory foods, no amount of supplementing will lead to a long term blood sugar resolution.

However, if you are putting in the work to change your diet and lifestyle, the right supplements can be powerful accelerators. They can help sensitize your cells to insulin, reduce inflammation, and protect your nerves from sugar damage.

In this guide, we are going to look at the science behind the most effective supplements for lowering blood sugar. We will look at what actually works, how much to take, and how to use them safely.

What “Lowering Blood Sugar” Actually Means

Before we talk about solutions, we need to define the problem. When we say “high blood sugar,” we are usually talking about three different things. A supplement might help one but not the other.

• Fasting Glucose: This is your blood sugar first thing in the morning, before you eat. High levels here often indicate that your liver is dumping too much sugar into your blood while you sleep (the “Dawn Phenomenon”) or that your baseline insulin resistance is high.
• Postprandial Glucose: This is your blood sugar spike 1–2 hours after a meal. High spikes damage blood vessels and nerves. This is often the first sign of trouble, even before fasting glucose goes up.
• Hemoglobin A1c (HbA1c): This is a 3-month average of your blood sugar. It tells us how much “sugar coating” (glycation) is stuck to your red blood cells. It reflects your long-term control.

Insulin Resistance, a primary mechanism leading to elevated blood glucose occurs when your cells become resistant to the action of the hormone insulin. Your pancreas responds by increasing production of insulin to compensate. If this goes on long enough, the pancreas loses it’s ability to keep up, and blood sugar rises.

Deep Dive: The Top Supplements for Lowering Blood Sugar

Here is the detailed breakdown of the nutrients that actually move the needle, based on research.

1. Magnesium

What it is: Magnesium is an essential mineral involved in more than 300 enzymatic reactions in the human body, serving as a fundamental cofactor for energy production and glucose metabolism.

How it may work: Magnesium is required for the activation of various enzymes in the glycolytic pathway and plays a vital role in the insulin signaling process. It is necessary for the proper function of the insulin receptor. When magnesium levels are low, the cells become less sensitive to insulin, leading to elevated blood sugar and compensatory hyperinsulinemia (high insulin levels).

Who it may help most: This mineral is especially helpful for individuals with high fasting glucose and those with metabolic syndrome. Since chronic stress and high-sugar diets deplete magnesium, most individuals with blood sugar issues are likely deficient.

What research shows: Systematic reviews and meta-analyses of randomized controlled trials (RCTs) indicate that magnesium supplementation significantly reduces fasting blood glucose levels. One analysis of trials found a significant reduction in fasting glucose and HbA1c.

Typical dose and how to take it: Studied doses range from 200 – 600 mg per day. The preferred forms are chelated, such as magnesium glycinate or citrate, which provide high bioavailability and are gentler on the digestive tract compared to magnesium oxide.

Safety, contraindications, and interactions: Individuals with kidney disease must avoid high-dose magnesium as the kidneys are responsible for its excretion. The most common side effect is loose stools or diarrhea.

Quality checklist: Opt for supplements that are third-party tested and free from grain-based fillers like corn maltodextrin. Ensure the form is a chelate rather than a cheap salt like oxide or carbonate.

Bottom line: Magnesium is a foundational nutrient for insulin sensitivity that should be prioritized in any metabolic support protocol.

2. Zinc

What it is: Zinc is a trace mineral that is highly concentrated in the pancreas, where it plays a unique role in the life cycle of the insulin hormone.

How it may work: Zinc is essential for the synthesis, storage, and secretion of insulin. Within the pancreatic beta cells, zinc binds to insulin molecules to form hexamers, which is the stable storage form of the hormone. Furthermore, zinc acts as an antioxidant, protecting the pancreas from the oxidative damage caused by chronic high blood sugar.

Who it may help most: Individuals with poor carbohydrate utilization or those displaying signs of “beta-cell fatigue” may benefit most from zinc.

What research shows: Meta-analyses show that zinc supplementation can improve fasting glucose, HbA1c, and insulin resistance (HOMA-IR) in adults with or at risk for type 2 diabetes. However, the relationship between serum zinc and glucose is complex, and excessive intake can be counterproductive.

Typical dose and how to take it: The typical studied range is 15 to 30 mg of elemental zinc per day. It is best taken with a meal to prevent nausea.

Safety, contraindications, and interactions: Chronic high doses of zinc (above 40 mg/day) may contribute to copper deficiency. Consider taking 1 mg of copper for every 15 mg of zinc daily to reduce this risk

Quality checklist: Look for zinc picolinate or citrate. Avoid products with excessive fillers or those that do not specify the elemental weight of the zinc.

Bottom line: Zinc is the “manufacturing partner” for insulin, making it indispensable for pancreatic health.

3. Chromium

What it is: Chromium is an essential trace mineral that has long been studied for its role in enhancing the action of insulin in the body.

How it may work: Chromium is believed to be a component of a biologically active molecule that helps the insulin receptor “bind” more effectively to insulin. This process enhances the transport of glucose from the blood into the cells. 

Who it may help most: Chromium appears most beneficial for individuals who have a baseline deficiency, often caused by diets high in refined sugars and grains, which increase the urinary excretion of chromium.

What research shows: Meta analysis of studies from human trials shows that chromium supplementation significantly reduces fasting blood glucose, HgA1c, and insulin.

Typical dose and how to take it: Studies often use 200 to 1,000 mcg per day of chromium chelates.

Safety, contraindications, and interactions: Chromium is generally considered safe.

Quality checklist: Chromium chelates (nicotinate, glycinate, picolinate) are the most bioavailable forms.

Bottom line: Chromium can be part of an effective strategy for supplemental blood glucose support and insulin receptor sensitivity in deficient individuals.

4. Vanadium

What it is: Vanadium is a trace element that has demonstrated significant “insulin-like” effects in laboratory, animal studies, and human studies.

How it may work: Vanadium salts mimic the actions of insulin by stimulating an insulin-independent pathway that moves glucose into cells. It acts as a potent inhibitor of certain phosphatases that usually “turn off” the insulin signal.

Who it may help most: Those with uncontrolled blood sugar levels despite other medial interventions.

What research shows: Animal models show dramatic blood sugar lowering.  Human studies show strong glucose-lowering effects with improvements in insulin sensitivity, but the studies to date have been done on small groups. 

Typical dose and how to take it:  Doses used in clinical research for diabetes range from 75–300 mg of vanadium daily.  Typical supplements contain much less vanadium (100-500 mcg).  Lower doses can be used safely without concern for medical supervision.  When combined with other ingredients like chromium and zinc, vanadium appears to have a synergistic effect with lower doses. 

Safety, contraindications, and interactions: Vanadium taken at higher doses is potentially toxic to the kidneys and can cause significant gastrointestinal distress, including abdominal cramping and diarrhea. Use caution and work with your doctor if you plan on taking higher doses.

Quality checklist: Ensure your supplement is free of synthetic or gluten related fillers.

Bottom line: Vanadium can be a helpful supplement for supporting healthy blood sugar, but taking higher doses is not recommended without supervision.

5. Vitamin D

What it is: Vitamin D is a fat-soluble vitamin that acts more like a hormone in the body, influencing thousands of genetic expressions related to immune and metabolic health.

How it may work: Vitamin D receptors (VDRs) are present on the insulin-producing beta cells of the pancreas. Vitamin D helps regulate the production and secretion of insulin and may improve the sensitivity of target tissues like the liver and muscles. It also reduces systemic inflammation, which is a major driver of insulin resistance.

Who it may help most: Individuals with with corresponding elevations in HgA1c as well as low serum 25 (OH) D, typically see the most benefit with supplementation.

What research shows: Observational studies consistently show that individuals with higher vitamin D levels have a lower risk of type 2 diabetes. Supplementation has been shown to improve glycemic control, particularly when correcting an existing deficiency.

Typical dose and how to take it: A common dose is 2,000 to 5,000 IU per day, though the dose should ideally be titrated based on 25(OH)D blood tests. Some patients require higher doses (8,000 – 10,000 IU/day) to see improved levels and benefits.

Safety, contraindications, and interactions: Vitamin D is generally very safe to take, and toxicity is rare when doses don’t exceed 10,000 IU/day for prolonged periods.  Consider taking with vitamin K to reduce the potential of elevated blood calcium.  If you have sarcoidosis, you should not take vitamin D without appropriate medical supervision.

Quality checklist: Choose Vitamin D3 (cholecalciferol) rather than the less active D2 (ergocalciferol).  Using an emulsified formulation will improve absorption.

Bottom line: Correcting a vitamin D deficiency is an essential, foundational step for long-term blood sugar stability.

6. Vitamin C

What it is: Vitamin C is a water-soluble antioxidant that protects the body from the oxidative stress that inevitably accompanies high blood sugar.

How it may work: Elevated blood sugar levels lead to the formation of reactive oxygen species (ROS) that damage blood vessels. Vitamin C neutralizes these free radicals. Furthermore, vitamin C competes with glucose for uptake into cells; therefore, when blood sugar is high, vitamin C levels inside the cells often drop.

Who it may help most: Vitamin C deficiency is common in diabetics.  Deficiency often manifest with high levels of oxidative stress along with vascular or microvascular complications (like kidney or eye issues).

What research shows: Diabetics tend to have significantly lower levels of vitamin C compared to healthy individuals. Supplementation can help restore antioxidant defenses.  Human trials have shown that treatment with vitamin C helps to lower fasting blood glucose, fasting insulin, HOMA-IR and HbA1c.

Typical dose and how to take it: Typical doses range from 500 mg to 1,000 mg per day.

Safety, contraindications, and interactions: Vitamin C may interfere with glucose meter measurements. Because the vitamin C molecule is chemically similar to glucose, it can cause falsely high readings on many home glucose monitors and continuous glucose monitors (CGMs). Take into consideration if you use these devices.  Discontinue vitamin C use 24 hours before getting your bloodwork done with your doctor to avoid falsely elevated glucose levels.

Quality checklist: Look for corn-free vitamin C (ascorbic acid) buffered with minerals to avoid potential grain-based allergens.

Bottom line: Vitamin C is vital for antioxidant protection against glucose induced damage while simultaneously having the ability to improve insulin and glucose control.  

7. Vitamin B1 (Thiamine)

What it is: Thiamine is a water-soluble B vitamin that serves as a critical coenzyme in the metabolism of carbohydrates and the production of ATP.

How it may work: Thiamine is required for the enzyme transketolase, which prevents the buildup of toxic sugar byproducts that lead to Advanced Glycation End-products (AGEs). AGEs are responsible for much of the nerve and vascular damage seen in diabetics.

Who it may help most: This vitamin is essential for those with diabetic neuropathy or kidney disease (nephropathy). The fat-soluble form, benfotiamine, is particularly effective for reaching the nervous system.

What research shows: Diabetics have a much higher rate of thiamine clearance from the kidneys, leading to widespread deficiency. Blood pressure medications commonly used in by diabetics can deplete vitamin B1.  Supplementation has been shown to reduce markers of glycation and support nerve function.

Typical dose and how to take it: Studied doses for benfotiamine often range from 100 to 300 mg per day.

Safety, contraindications, and interactions: It is generally very safe and non-toxic even at higher doses.

Quality checklist: Prioritize benfotiamine over standard thiamine HCl for superior tissue distribution.

Bottom line: Thiamine is the primary defense against the “browning” or glycation of the body’s tissues caused by high sugar.

8. Vitamin B6 (Pyridoxine)

What it is: Vitamin B6 is a cofactor for more than 100 enzymes, playing a central role in protein and glucose metabolism.

How it may work: It is necessary for the process of gluconeogenesis and the breakdown of glycogen in the liver and muscles. It also helps manage levels of homocysteine, a marker of inflammation.

Who it may help most: Individuals with high inflammation, elevated homocysteine, or those displaying early signs of metabolic disruption.  Individuals with high levels of post prandial blood glucose.

What research shows: Vitamin B6 deficiency has been linked with impaired gluconeogenesis (a process that helps keep blood glucose stable during fasting and exercise).  Deficiency is also linked to impaired glucose tolerance a reduced insulin levels.  Human research shows that vitamin B6 significantly lowers post prandial glucose.  Additionally, B6 treatment trials show that it has the ability to lower fasting glucose, HgA1c, and improve insulin levels.

Typical dose and how to take it: Use the P-5′-P form.  Dose can range from 50-300 mg per day.  When exceeding 50 mg, work with a doctor to monitor for potential toxicity.

Safety, contraindications, and interactions: Human studies use the P-5’P form of vitamin B6.  No toxicity was reported with this form in doses up to 300 mg/day.  High doses can cause sensory peripheral neuropathy – ie. numbness and tingling in the hands and feet.  This is typically associated with a form of B6 called pyridoxine HCl.  Consider avoiding this type of B6 to reduce risk.

Quality checklist: Use the active pyridoxal-5′-phosphate (PLP) form, which is not associated with B6 toxicity

Bottom line: B6 plays a critical role in glucose and insulin regulation.  It is commonly deficient in diabetics, and could play a vital role with doctor guided treatment.

9. Biotin (Vitamin B7)

What it is: Biotin is a water-soluble B vitamin that acts as a cofactor for enzymes that manage the synthesis of glucose and fatty acids.

How it may work: Biotin helps regulate the expression of the glucokinase enzyme in the liver, which is the “first step” in trapping glucose for storage. It may also improve the function of pancreatic beta cells.

Who it may help most: Patients with both Type I and Type II diabetes with uncontrolled blood sugar.

What research shows: Meta-analysis of human studies show that biotin supplementation in doses ranging from 1.5-9 mg daily can help reduce fasting blood glucose and triglyceride levels.

Typical dose and how to take it: 1,500 to 9000 mg per day are typical doses used in studies.

Safety, contraindications, and interactions: Biotin is very safe to take.  Be aware that it can interfere with some lab tests. It can cause falsely high or low results in thyroid tests (TSH, T4), troponin (heart attack marker), and pregnancy tests. It should be stopped at least 72 hours before performing these specific labs.

Quality checklist: Avoid potential grain based fillers commonly found in OTC supplements.

Bottom line: Biotin supports metabolic enzymes that regulate blood glucose metabolism, and can be an effective nutritional support supplement.

10. Inositol

What it is: Inositol is a sugar-like compound (sometimes called Vitamin B8) that serves as a vital component of cell membranes and a “second messenger” for hormones.

How it may work: When insulin “knocks” on the door of a cell, inositol molecules inside the cell receive that signal and tell the cell to open up and let glucose in. A deficiency in these “messengers” is a primary cause of insulin resistance.

Who it may help most: Diabetics *type I and II) as well as women with Polycystic Ovary Syndrome (PCOS), gestational diabetes, and individuals with high triglycerides and weight gain around the abdomen.

What research shows: Systematic reviews and meta-analyses show that myo-inositol is highly effective at improving insulin sensitivity, lowering fasting glucose, and restoring hormonal balance in women with PCOS.

Typical dose and how to take it: The standard dose is 2,000 to 4,000 mg per day, often taken in two divided doses.

Safety, contraindications, and interactions: It is exceptionally safe, with only minor GI side effects reported at high doses.

Quality checklist: Look for myo-inositol.  Avoid gluten based fillers.

Bottom line: Inositol is one of the best-researched natural tools for restoring cellular communication and insulin sensitivity.

11. Alpha-Lipoic Acid (ALA)

What it is: ALA is a unique antioxidant that is both fat- and water-soluble, allowing it to penetrate every part of the cell and regenerate other antioxidants like Vitamin C and E.

How it may work: ALA stimulates the “GLUT4” transporters in the cell membrane. This allows glucose to enter the cells even if the insulin receptors are not working perfectly. 

Who it may help most: Individuals with diabetic neuropathy (nerve pain) or those with chronic high HbA1c levels.

What research shows: Numerous studies have confirmed that ALA can significantly improve nerve conduction and reduce symptoms like burning, itching, and numbness in the extremities. It also improves insulin sensitivity in obese patients.

Typical dose and how to take it: Studied doses range from 600 to 1,200 mg per day. It is best taken on an empty stomach for maximum absorption.

Safety, contraindications, and interactions: ALA is very potent. It can increase the risk of hypoglycemia if taken alongside insulin or other glucose-lowering drugs.

Quality checklist: Look for either lipoic acid combined with biotin, or R-Lipoic Acid.

Bottom line: ALA is a dual-action powerhouse for both glucose control and nerve protection.

12. CoQ10

What it is: Coenzyme Q10 is a fat-soluble antioxidant found in every cell of the body, where it is required for the production of energy (ATP) in the mitochondria.

How it may work: If the mitochondria – the cell’s “engines” – are not working, the body cannot burn glucose efficiently. CoQ10 ensures that the “engine” is tuned up. It also protects the mitochondria from the inflammatory damage associated with insulin resistance.

Who it may help most: Individuals taking statin medications, which block the production of CoQ10, and those with chronic fatigue alongside blood sugar issues.

What research shows: While the direct blood sugar lowering effect is modest, its role in preventing oxidative damage to the heart and nerves is significant.

Typical dose and how to take it: 100 to 400 mg per day is the typical dose range recommended.

Safety, contraindications, and interactions: It is safe for most but can interfere with blood-thinning medications.

Quality checklist: Choose ubiquinol rather than ubiquinone, as ubiquinol is the pre-converted, highly absorbable form.

Bottom line: CoQ10 is essential for metabolic energy and protecting the body from the side effects of conventional heart medications.

13. Berberine

What it is: Berberine is a natural alkaloid found in several plants, such as goldenseal and barberry, and has been used for centuries in traditional medicine for its profound metabolic effects.

How it may work: Berberine activates an enzyme called AMPK, often called the body’s “metabolic master switch.” Activating AMPK mimics the effects of exercise: it tells the body to burn fat, stop producing excess glucose in the liver, and move glucose into the muscles.

Who it may help most: Individuals with high HbA1c, fatty liver, high triglycerides, and obesity.

What research shows: Head-to-head clinical trials have shown that berberine is comparable in efficacy to the drug metformin. In one study, 1,500 mg of berberine per day was as effective as metformin at lowering HbA1c, fasting glucose, and post-meal glucose.

Typical dose and how to take it: 500 mg taken three times daily, about 30 minutes before meals.

Safety, contraindications, and interactions: Berberine can cause GI issues (constipation or diarrhea) in some.  If you are already taking blood sugar medications, talk with your doctor before starting berberine.

Quality checklist: Ensure the supplement comes from a reputable company and is free from grain-based fillers.

Bottom line: Berberine is arguably the single most effective botanical for correcting insulin resistance and lowering high blood sugar.

**WARNING** If you are currently taking blood sugar-lowering medications – including insulin, sulfonylureas (like Glipizide), meglitinides, GLP-1 agonists (like Ozempic), SGLT2 inhibitors, or metformin, adding effective supplements can cause your blood sugar to drop too low (hypoglycemia). This can be dangerous. It is important that you work with your doctor to monitor your numbers closely, as your medication dosage may need to be reduced.

How to Choose the Right Supplement for Your Pattern

With so many possibilities and patterns, the following table will help you narrow down how to prioritize which supplements might help support you best.  Ultimately it is recommended that nutritional testing is performed so that the approach can be customized to your needs.

6 Lifestyle Factors You Need to Also Consider

You can take as many supplements as you want, but if you want enhanced results you should be focusing on the following diet and lifestyle changes.

1. Follow the No Grain No Pain Diet: Removing grains, hidden sugars, and ultra-processed foods is the only way to stop the “fire” of inflammation. A grain-free approach prevents the hidden carbohydrate loads and immune-triggering proteins found in modern wheat and corn.

2. Protein and Fiber Prioritization: Consuming high-quality animal protein and fiber from non-starchy vegetables slows down the entry of sugar into the blood and triggers the body’s natural satiety signals.

3. Sleep and Stress Management: High cortisol levels from poor sleep or chronic stress directly signal the liver to dump glucose into the blood. No amount of berberine can overcome a chronic state of “fight or flight”.

4. Strategic Movement: Walking for 10 to 15 minutes after a meal uses the muscles to “soak up” glucose, significantly reducing post-meal insulin needs.

5. Strength Training: Building lean muscle increases the number of “glucose sinks” in the body. More muscle equals more metabolic flexibility.

6. Sunshine:  Sunshine increases energy, allows for natural vitamin D production, helps regulate stress hormones, and helps your body make the sleep hormone, melatonin.

Testing: Measure The Right Things

Most doctors only run A1c and Glucose. That is not enough. To truly understand your metabolic health, request:

• Intracellular Nutrient Analysis (INA):  This test measures all of the above nutrients except berberine.
• Hemoglobin A1c: (Goal: < 5.6%)
• Fasting Insulin: (Goal: < 5 uIU/mL). This rises years before blood sugar does.
• Fasting Glucose: (Goal: 60–90 mg/dL).
• C-Peptide: Tells us if your pancreas is still making insulin.
• Vitamin D (25-OH): (Goal: 50–100 ng/mL).
• Homocysteine: Marker of inflammation and B-vitamin status.
• Lipid Panel: Look specifically at the Triglyceride to HDL ratio. (Goal: < 2:1).

Optional but recommended: Use a Continuous Glucose Monitor (CGM) for 30 days to see exactly how specific foods affect you.

A Note on Medication Nutrient Depletion

If you are already on meds, they might be causing deficiencies that make your control worse.

• Metformin: Depletes Vitamin B12 and Folate which can cause anemia and neuropathy.
• Statins: Deplete CoQ10 which contributes to fatigue, heart failure, and hypertension
• Sulfonylureas: Deplete CoQ10.
• Diuretics (Blood Pressure): Deplete Magnesium, Potassium, Zinc, and Vitamin B1 leading to increased risk of hypertension and heart disease.

If you take these drugs, supplementation is often necessary to prevent side effects.

FAQ

Key Takeaways

The road to metabolic health requires moving beyond the surface-level management of symptoms. By focusing on a grain-free, nutrient-dense diet and utilizing targeted supplements like berberine, magnesium, and alpha-lipoic acid, individuals can address the root causes of blood sugar dysfunction.

• Diet is Primary: Supplements cannot compensate for a diet high in grains and processed sugars.   

• Test, Don’t Guess: Use specialized testing to identify exactly which minerals and vitamins the body is missing. 

• Prioritize Quality: Avoid grain-based fillers and low-absorption forms of vitamins and minerals.

• Be Patient: Metabolic repair takes time; expect to see the most significant changes after three to six months of consistency.

  
  

The post What are the most effective supplements for lowering blood sugar? appeared first on Gluten Free Society.

Most people think celiac disease is obvious – constant diarrhea, dramatic weight loss, and severe stomach pain. But in the real world, early warning signs of celiac disease often shows up in young adults as “nothing dramatic”… until years later when the damage is done. That diagnostic delay matters, because untreated celiac can lead to nutrient deficiencies, bone loss, infertility, neurological issues, and an increased risk of early death.

A newly published large-scale study asked a simple, important question:

Are there subtle lab or clinical clues that appear years before someone is officially diagnosed with celiac disease?

Turns out—yes. And many of them are hiding in plain sight on routine lab work.

What the researchers did (in plain English)

The investigators used a large healthcare database (Clalit Health Services) and looked at over 430,000 adults ages 18–40. They identified early warning signs of people who eventually developed celiac disease based on both:

• a celiac diagnosis code, and
• positive celiac blood tests (serology).

Then they tracked common labs and clinical features for up to 7 years before diagnosis to see what patterns showed up early before most doctors were even thinking “celiac.”

The Big Takeaway: Celiac Whispers Before it Screams

The most important finding is this:

Subtle changes in blood counts, liver enzymes, and body weight can show up years before a formal celiac diagnosis.

These weren’t always “abnormal” labs. Many were low-normal or high-normal values that often get shrugged off.

How Early Were These “Pre-Celiac” Clues Showing Up?

This is what makes the study so valuable:  The lab “breadcrumbs” were detectable as early as 7 years before diagnosis.

And at the time of diagnosis:

• ~70% of people diagnosed with celiac had at least one of these subtle lab flags.
  Even 7 to 3 years before diagnosis.

That means many people are walking around for years with early, detectable signs while being told their labs are “fine.”

What You Should Do With This Information (Practical Steps)

If you or someone you love has any combination of the following:

• hemoglobin drifting down (especially iron-deficiency pattern / low MCV)
• persistently “slightly high” ALT or AST
• unexplained lean body weight or difficulty maintaining weight (malnutrition from malabsorption)
• recurring GI symptoms (even if labeled IBS)
• infertility concerns alongside odd labs
• or a known higher-risk genetic background

Ask your doctor about celiac screening.

Common first-line tests typically include tissue transglutaminase antibodies (tTG) and related blood markers, and ideally total IgA so IgA deficiency doesn’t create a false negative scenario (the study itself notes this as a limitation for some cases).

Important: Don’t stop eating gluten before testing, or you can make results falsely negative. Stay on gluten until testing is complete.

A Quick Word on Limitations 

This was a retrospective database study, meaning:

• it relied on diagnostic coding and recorded labs
• mild symptoms may not have been consistently documented

Still, the sample size was massive, and the patterns match what clinicians often see: early warnings signs of celiac disease frequently present through anemia patterns, mild liver enzyme changes, and subtle malabsorption signals long before anyone calls it “celiac.”

The Bottom Line

If your body is dropping hints – i.. low-normal iron labs, “mystery” liver enzymes, IBS symptoms that won’t resolve, and fatigue that doesn’t match your life don’t accept vague reassurance as a diagnosis.

Celiac disease doesn’t always announce itself with a megaphone. Sometimes it just leaves a paper trail in your labs.

And this study shows that trail can start up to 7 years early.  If you think gluten may be part of your problem, take the gluten quiz or consider genetic testing through Gluten Free Society to help you determine whether a gluten free diet is right for you.

Frequently Asked Questions

What is silent celiac?

Silent celiac is celiac disease that does not always show up with the classic digestive symptoms people expect. You may not have severe diarrhea or dramatic stomach pain, but gluten can still be triggering immune damage in the small intestine. In many cases, the earliest clues show up as nutrient deficiency patterns, unexplained fatigue, odd lab work, low body weight, infertility, bone loss, or recurring symptoms that get brushed off as “nothing serious.”

Can you have celiac disease without obvious digestive symptoms?

Yes. That is one of the biggest reasons celiac disease is missed for years. Some people have little to no obvious gut distress, while others have symptoms that come and go, such as bloating, abdominal discomfort, constipation, loose stools, or an IBS label that never fully explains the problem. The absence of major digestive symptoms does not rule celiac out.

What are the early warning signs of celiac disease?

Early warning signs can include low-normal hemoglobin, low MCV suggesting small red blood cells, mild iron deficiency patterns, slightly elevated ALT or AST, trouble maintaining weight, fatigue, recurrent digestive symptoms, infertility, and other subtle signs of malabsorption. The key point is that these clues may appear years before a formal diagnosis, even when they are not flagged as dramatically abnormal.

Can low iron be an early sign of celiac disease?

Absolutely. One of the most important early clues is an iron-deficiency pattern, especially when there is no obvious cause. If your hemoglobin is drifting down, your red blood cells are getting smaller, or your iron status keeps looking borderline despite supplementation, celiac disease should be on the shortlist. Gluten-driven intestinal damage can impair iron absorption long before the disease is formally diagnosed.

Can celiac disease cause elevated liver enzymes?

Yes. Mildly elevated liver enzymes can be one of the quiet signs of celiac disease. If ALT or AST keep coming back a little high and there is no clear explanation, gluten-related inflammation and malabsorption deserve consideration. This is one of the patterns that is often dismissed when it should be investigated more carefully.

Can celiac disease look like IBS?

Yes, and this happens all the time. Chronic bloating, gas, abdominal pain, diarrhea, constipation, or unpredictable digestion are often labeled IBS, but in some people the real issue is celiac disease. If symptoms keep recurring and no one has done a proper celiac workup, that is a gap that needs to be addressed.

How long can celiac disease go undiagnosed?

It can go undiagnosed for years. The article highlights research showing that subtle clues may appear as early as 7 years before diagnosis. That means many people are being told their labs are “fine” while their body is leaving a very real paper trail.

Who is at higher risk for silent celiac?

People with unexplained iron deficiency, chronic digestive issues, infertility concerns, low body weight, family history of celiac disease, or associated genetic and autoimmune conditions are at higher risk. Certain chromosomal conditions, such as Down syndrome and Turner syndrome, also carry a significantly higher risk and warrant more proactive screening.

What tests are used to screen for celiac disease?

Common first-line screening usually includes tissue transglutaminase antibodies, often called tTG, along with related antibody markers and a total IgA level to help rule out false negatives in people with IgA deficiency. In some cases, genetic testing can also help clarify whether a gluten-free diet investigation makes sense, especially when the picture is confusing.

What should you do if you think you have silent celiac?

Ask your doctor to evaluate you.  Especially if you have unexplained anemia patterns, odd liver enzymes, recurring IBS-type symptoms, trouble maintaining weight, infertility concerns, or a family history of celiac disease, ask for proper screening. The earlier you catch it, the better your odds of preventing long-term complications.
