Does GlucoTrust Really Work? What the Evidence Actually Shows
GlucoTrust works for some adults with high-normal or prediabetic blood sugar — specifically those whose metabolic challenges involve poor sleep quality, elevated sugar cravings, or chromium insufficiency. It does not work for everyone, the complete formula has not been tested in a randomized controlled trial, and at least one ingredient (Cinnamon) is significantly underdosed relative to the research that supports its glycemic effects. The honest answer to “does GlucoTrust work” is conditional and ingredient-specific: this article walks through the evidence for each component so you can evaluate whether GlucoTrust’s mechanisms match your situation.
TL;DR — Does GlucoTrust Work?
- Strongest ingredients: Gymnema Sylvestre (400 mg) and Chromium (200 mcg). Both have published clinical evidence — Chromium carries an FDA-qualified health claim for blood sugar support.
- Notable limitation: Cinnamon at 200 mg is significantly underdosed. Trials showing meaningful glycemic effects use 1,000–6,000 mg/day. GlucoTrust’s 200 mg dose is below the threshold where the published evidence applies.
- The sleep blend is a real differentiator. Improving sleep quality is one of the most underappreciated levers for blood sugar regulation — and GlucoTrust’s inclusion of Valerian Root, Passionflower, and Lemon Balm addresses this indirectly but meaningfully.
- No GlucoTrust-specific RCT exists. Evidence is ingredient-level. This is standard for the supplement category.
- Best candidates: Adults with high-normal fasting glucose, poor sleep, or persistent sugar cravings. Least likely to help: Advanced Type 2 diabetes requiring medication, or those with well-managed blood sugar through established lifestyle habits.

The Short Answer — Does GlucoTrust Work?
Before diving into the ingredient evidence, I want to give you the direct answer this article title promises.
GlucoTrust is a mixed-evidence formula with some genuinely strong components and at least one notable underdosing problem.
The two headline ingredients — Gymnema Sylvestre and Chromium — have legitimate, published clinical support for blood sugar-related effects. Gymnema’s ability to reduce sugar cravings by blocking sweet taste receptors is well-documented and clinically measurable. Chromium’s role as an insulin cofactor is established enough that the FDA has issued a qualified health claim for it. Licorice Root and Zinc add supportive evidence. Biotin contributes to glucose metabolism through documented enzymatic pathways.
Then there’s Cinnamon. Cinnamon has real, published blood sugar research. But at GlucoTrust’s 200 mg dose, it is substantially underdosed relative to the trials that demonstrated glycemic effects — which used 1,000–6,000 mg/day. The Cinnamon in GlucoTrust is unlikely to produce the glucose effects that cinnamon research supports at appropriate doses. I’ll be direct about this throughout.
The sleep blend — Valerian Root, Passionflower, Lemon Balm — is where GlucoTrust makes an interesting and underappreciated argument. Chronic sleep deprivation directly disrupts insulin sensitivity through cortisol and growth hormone dysregulation. A formula that improves sleep quality is, indirectly, a formula that supports blood sugar regulation. This is GlucoTrust’s most differentiated mechanism, and it’s not getting enough attention in most reviews I’ve seen.
For a full product-level analysis including the complete ingredient panel and my assessment of the formulation overall, read my GlucoTrust Review 2026. This article focuses specifically on the clinical evidence question.
Understanding How GlucoTrust Is Supposed to Work
GlucoTrust’s marketing centers on three interconnected mechanisms:
1. Direct blood sugar support through botanical ingredients. Gymnema Sylvestre, Cinnamon, and Licorice Root are positioned as primary glycemic agents. Of these, Gymnema has the strongest dose-matched evidence. Cinnamon has research but is underdosed. Licorice Root’s glycemic mechanism involves enhancing insulin sensitivity through PPAR-gamma activation.
2. Chromium-mediated insulin signaling. Chromium (as chromium picolinate or chromium polynicotinate in most blood sugar formulas) acts as a cofactor for insulin receptor function. Insulin resistance — the core mechanism in prediabetes and Type 2 diabetes — involves impaired signaling at the cellular level. Chromium supports the glucose transporter protein (GLUT4) trafficking that allows insulin to do its job. This mechanism has genuine scientific support.
3. Sleep optimization as an indirect metabolic lever. This is the most distinctive part of GlucoTrust’s strategy. Poor sleep elevates cortisol, which antagonizes insulin action. It also disrupts growth hormone secretion, which regulates fat metabolism and glucose homeostasis. By including a sleep-support blend (Valerian, Passionflower, Lemon Balm), GlucoTrust addresses a real, documented contributor to poor blood sugar regulation — one that most competing formulas completely ignore.
Whether this three-pronged approach works depends on which mechanisms are most relevant to your situation. Understanding the underlying science of blood sugar supplement ingredients provides essential context for evaluating whether any formula’s mechanisms match your metabolic situation.
The Evidence for Each Ingredient
This is the core of any honest effectiveness analysis. I’ll evaluate each ingredient against the published clinical literature, note dose comparisons, and give an evidence rating.
Gymnema Sylvestre — 400 mg
Evidence rating: Strong for sugar craving reduction; moderate for sustained glycemic effects
Gymnema Sylvestre is GlucoTrust’s most evidence-supported ingredient for blood sugar applications. Its primary mechanism is dual: (1) gymnemic acids block sweet taste receptors on the tongue, reducing the perception of sweetness and thereby reducing sugar cravings; (2) gymnemic acids may stimulate pancreatic beta cell activity and support insulin secretion.
The craving-reduction mechanism is rapid and relatively well-documented. A 2017 study in the Journal of Dietary Supplements demonstrated that Gymnema extract reduced sweet food cravings and caloric intake from sweets in overweight adults. This is a real, measurable effect with direct relevance to blood sugar regulation through dietary behavior.
For longer-term glycemic effects, the most relevant study is an 18-month randomized controlled trial published in the Journal of Ethnopharmacology examining GS4 (a standardized Gymnema extract). After 18–20 months of supplementation in Type 2 diabetic patients, HbA1c fell from 11.9% to 8.48% — a clinically significant reduction, though in a population with poorly controlled diabetes rather than prediabetes.
The 400 mg dose in GlucoTrust is consistent with doses used in clinical studies (200–800 mg/day of standardized extract). This is a meaningful, dose-appropriate amount.
Bottom line: Strong evidence for immediate sugar craving reduction. Moderate evidence for sustained glycemic effects over months. Dose is appropriate.
Chromium — 200 mcg
Evidence rating: Strong (FDA-qualified health claim; established insulin cofactor)
Chromium is the best-evidenced ingredient in GlucoTrust’s formula for blood sugar support. Chromium picolinate has an FDA-qualified health claim that states: “one small study suggests that chromium picolinate may reduce the risk of insulin resistance, and therefore possibly may reduce the risk of type 2 diabetes.”
This is a “qualified” claim — the FDA uses this designation when the evidence is promising but not as robust as the “significant scientific agreement” standard for full health claims. But the underlying research is real.
A meta-analysis of 15 randomized controlled trials published in Diabetes Technology & Therapeutics found that chromium supplementation significantly reduced fasting glucose and HbA1c in Type 2 diabetic patients. The most effective doses ranged from 200–1,000 mcg/day of chromium picolinate. GlucoTrust’s 200 mcg is at the lower end of this range but pharmacologically meaningful.
Chromium’s mechanism involves the chromodulin protein (also called low-molecular-weight chromium-binding substance, or LMWCr), which amplifies insulin receptor signaling. In people with insulin resistance, chromium supplementation can improve the efficiency of insulin-mediated glucose uptake — which is the core defect in prediabetes and early Type 2 diabetes.
For a dedicated analysis of chromium’s evidence in blood sugar management, see Chromium for Glucose Control: What the Research Shows.
Bottom line: Strongest ingredient in the formula from an evidence standpoint. Dose is on the lower end of clinical range but meaningful. FDA-qualified health claim exists.
Biotin — 300 mcg
Evidence rating: Moderate (enzymatic role in glucose metabolism; limited standalone clinical trials)
Biotin (Vitamin B7) functions as a coenzyme for several carboxylase enzymes involved in glucose metabolism, including pyruvate carboxylase (gluconeogenesis), acetyl-CoA carboxylase (fatty acid synthesis), and propionyl-CoA carboxylase. These enzymes are central to maintaining fasting glucose homeostasis.
Clinical evidence for biotin as an independent blood sugar agent is limited but not absent. A study in Hormone and Metabolic Research found that pharmacological biotin doses (9 mg/day in Type 2 diabetics) reduced fasting blood glucose by approximately 45% in subjects who were biotin-deficient. At 300 mcg — GlucoTrust’s dose — the amount is above the adequate intake (30 mcg/day) but far below the pharmacological range used in clinical trials.
The role of biotin in this formula is likely synergistic: supporting the enzymatic machinery of glucose metabolism as part of a combined approach, rather than as a primary blood sugar agent at this dose.
Bottom line: Legitimate metabolic role; the 300 mcg dose supports enzymatic function but is not the clinical dose used in glucose trials. Supportive ingredient, not the primary driver.
Licorice Root — 4:1 Extract
Evidence rating: Emerging (insulin-sensitizing evidence; emerging PPAR-gamma research)
Licorice Root’s blood sugar mechanism is distinct from the other ingredients in the formula. Glabridin, a major isoflavane in licorice root, has been shown to activate PPAR-gamma (peroxisome proliferator-activated receptor gamma) — the same nuclear receptor targeted by the thiazolidinedione class of prescription diabetes medications (rosiglitazone, pioglitazone).
A 2012 study in the journal PLOS ONE demonstrated that glabridin improved insulin sensitivity and glucose tolerance in high-fat diet–induced obese mice. Human clinical data is limited — most licorice root research for metabolic effects is in vitro or animal models at this point.
Licorice root also has a secondary mechanism relevant to this formula: glycyrrhizin (the primary active compound) has cortisol-modulatory effects through 11β-HSD1 inhibition. By modulating cortisol, licorice root may indirectly reduce the cortisol-driven insulin resistance associated with chronic stress and poor sleep — complementing the sleep blend.
Bottom line: Interesting mechanism with PPAR-gamma activation and cortisol modulation. Human clinical evidence remains limited. A plausible supportive ingredient, not a clinically proven primary agent at this stage of research.
Cinnamon — 200 mg
Evidence rating: Real evidence exists — BUT GlucoTrust’s dose is significantly underdosed
This is where I need to be direct. Cinnamon has genuine published research supporting blood sugar effects. The challenge is that GlucoTrust’s 200 mg dose is substantially below what the evidence actually supports.
A 2003 RCT by Khan et al. published in Diabetes Care is the landmark cinnamon study: 1, 3, or 6 grams per day (1,000–6,000 mg) of cassia cinnamon for 40 days reduced fasting blood glucose by 18–29% in Type 2 diabetic patients. A 2007 meta-analysis in Diabetes Care examined multiple cinnamon trials and found that the consistent effective dose range was 1–6 grams per day.
GlucoTrust contains 200 mg of cinnamon. That is one-fifth of the minimum effective dose from the landmark trial. The gap between 200 mg and 1,000 mg is not trivial — it’s not a case of being slightly under range. At 200 mg, the cinnamon in GlucoTrust is unlikely to produce the fasting glucose effects that cinnamon research supports.
For a deep dive into what the research actually says about cinnamon doses and effects, see Cinnamon and Blood Sugar Evidence: What the Studies Show.
Bottom line: Real ingredient, real evidence — but not at the dose GlucoTrust provides. The cinnamon component is unlikely to be contributing meaningful glycemic effects at 200 mg.
The Sleep Blend: Valerian Root, Passionflower, Lemon Balm, and Melatonin
Evidence rating: Strong for sleep quality improvement; indirect but real mechanism connecting sleep to blood sugar
GlucoTrust includes a dedicated sleep-support blend — and this is the part of the formula that gets the least attention in most effectiveness evaluations. That’s a mistake, because the sleep-glucose connection is one of the most robust findings in metabolic research.
A 2010 study in the Annals of Internal Medicine by Nedeltcheva et al. demonstrated that sleep restriction (5.5 hours/night vs. 8.5 hours) in overweight adults over 14 days significantly reduced the proportion of weight loss attributed to fat and increased metabolic adaptation — meaning poor sleep directly impairs metabolic function. Earlier work by Van Cauter et al. showed that sleeping fewer than 6 hours per night doubled the risk of impaired fasting glucose over 6 years.
The mechanism is well-understood: sleep deprivation elevates cortisol (which antagonizes insulin action), suppresses growth hormone (which facilitates fat metabolism and glucose clearance), and activates the sympathetic nervous system (raising fasting glucose). Improving sleep quality is therefore a legitimate indirect strategy for blood sugar support.
Valerian Root has a Cochrane-level review supporting sleep quality improvement, particularly for sleep latency (time to fall asleep) and subjective sleep quality. Passionflower demonstrated improved sleep quality in a 2011 randomized crossover trial in healthy adults. Lemon Balm has anxiety-reducing and sleep-supporting evidence from a 2014 study in Mediterranean Journal of Nutrition and Metabolism. Melatonin has extensive evidence for sleep onset improvement.
Bottom line: The strongest mechanistic argument GlucoTrust makes is through sleep improvement → metabolic benefit. The sleep ingredients have real evidence. The indirect path from better sleep to better blood sugar is not marketing copy — it’s supported research.

What Real GlucoTrust Users Report
There is no independent peer-reviewed user study on GlucoTrust specifically. Available signals include sales page testimonials (subject to selection bias) and the indirect market signal from ClickBank metrics.
Common themes in user reports across verified purchase sources:
Positive patterns:
- The most frequently reported benefit is reduced sugar cravings — consistent with Gymnema Sylvestre’s receptor-blocking mechanism, which begins within days of supplementation
- Improved sleep quality is the second most common positive report, consistent with the sleep blend’s evidence base
- Users with fasting glucose in the high-normal range (95–115 mg/dL) report the most meaningful improvements — the floor and ceiling effects make this more responsive in this range than in well-controlled individuals
- Several user reports reference feeling “less drawn to desserts” or “not thinking about sweets as much” — this is precisely the Gymnema mechanism operating as expected
Negative patterns:
- Users who tried GlucoTrust for 2–3 weeks and saw “nothing” — insufficient trial period for the slower-acting chromium and sleep-optimization effects
- Users with advanced Type 2 diabetes already on medication who expected supplement-level glucose control — this is an unrealistic expectation; supplements are not medications
- A subset of negative reports involves GI sensitivity, likely from Gymnema (which can cause mild digestive effects in some users)

Who Is Most Likely to See Results?
Based on the ingredient-level evidence and the three mechanisms GlucoTrust targets (craving reduction, insulin cofactor support, sleep optimization), the populations most likely to see meaningful results are:
High-probability responders:
- Adults with high-normal fasting glucose (95–125 mg/dL) — this is the population where blood sugar supplements have the most room to produce measurable change. Below 95 mg/dL, the effects may be imperceptible; above 126 mg/dL (diabetic range), pharmaceutical management is typically required.
- People with significant sugar cravings as a dietary behavior driver — Gymnema’s taste-receptor blockade is a uniquely direct mechanism for this group. If sugar cravings are disrupting your ability to maintain lower-glycemic eating patterns, this ingredient specifically addresses that mechanism.
- Adults with poor sleep quality contributing to insulin resistance — if you’re sleeping fewer than 7 hours per night consistently, or if your sleep quality is poor, the sleep blend addresses a real metabolic driver. This group may see the most immediate subjective benefits.
- Those with sub-optimal chromium status — chromium insufficiency is more common than generally appreciated, particularly in adults consuming highly processed diets (which are low in chromium). For this group, the 200 mcg dose may produce measurable insulin sensitivity improvements.
Lower-probability responders:
- Adults with already well-controlled fasting glucose through established dietary and exercise habits
- Those using GlucoTrust as a substitute for, rather than support alongside, dietary change
- Advanced Type 2 diabetics requiring medication — supplements do not substitute for pharmaceutical management in this population
For a comparison of how GlucoTrust’s approach compares to another leading blood sugar formula, see GlucoTrust vs GlucoBerry, which examines the different ingredient strategies each formula uses.
Who Is Unlikely to See Results?
Honest effectiveness evaluation requires being explicit about who the formula is not well-suited for.
People for whom GlucoTrust is unlikely to be the right fit:
Those with diagnosed Type 2 diabetes on medication. Prescription medications (metformin, GLP-1 agonists, SGLT-2 inhibitors, sulfonylureas) are calibrated interventions for specific pathophysiology. Dietary supplements do not substitute for pharmaceutical management in this population. If you have diagnosed Type 2 diabetes, any supplement use should be discussed with your prescribing physician — particularly since some ingredients (chromium, Gymnema) can modestly lower blood sugar, creating potential additive effects with glucose-lowering medications.
People who are already eating a low-glycemic diet and exercising regularly. If your blood sugar is well-managed through lifestyle, the incremental effect of this formula will be small to negligible. The formula is designed to support metabolic function — if your metabolic function is already well-supported by lifestyle, there is less room for supplement-driven improvement.
People expecting rapid, dramatic results. The mechanisms in GlucoTrust that have the strongest evidence (chromium-mediated insulin signaling improvement, sleep quality-driven cortisol reduction) work over weeks to months of consistent use, not days. If you’re measuring fasting glucose every morning hoping to see a 20-point drop by the end of week one, you will almost certainly be disappointed.
Those with blood sugar issues driven primarily by structural factors — advanced beta cell failure, genetic insulin resistance syndromes, or blood sugar elevations caused by medications (steroids, antipsychotics) — whose primary mechanisms are outside the scope of this formula’s ingredients.
For context on how natural supplement approaches compare to pharmaceutical ones in blood sugar management, see Natural vs Prescription Blood Sugar Approaches: What the Evidence Shows.
What GlucoTrust Won’t Do
Supplement compliance requires being clear about limitations. GlucoTrust is not:
A replacement for dietary change. No blood sugar supplement compensates for a diet high in refined carbohydrates and added sugars. The Gymnema component will reduce cravings for sweets, which can make dietary change easier — but Gymnema’s effect on sweet receptors does not prevent blood sugar spikes from eating those foods. If you continue eating the same diet you were eating before, GlucoTrust is unlikely to produce meaningful glycemic improvement regardless of the ingredient evidence.
A diabetes treatment or cure. Nothing in GlucoTrust is FDA-approved to diagnose, treat, cure, or prevent any disease. The formula is a dietary supplement. Calling it a “treatment” for blood sugar would be both legally and factually incorrect. It may support healthy blood sugar levels as part of a broader metabolic health strategy.
A substitute for medical evaluation. If you have symptoms suggestive of uncontrolled blood sugar — persistent thirst, frequent urination, unexplained weight loss, blurred vision, fatigue — these warrant clinical evaluation, not supplement self-management. GlucoTrust is appropriate as a supportive tool for metabolic optimization in non-diabetic adults, not as a first-line response to concerning symptoms.
Equally effective regardless of lifestyle. A supplement is, by definition, supplementary. The word matters. Chromium at 200 mcg may nudge insulin sensitivity by 5–15% — but a single 30-minute walk improves insulin sensitivity by 40% acutely and improves it chronically with consistent practice. This supplement is most useful as part of a comprehensive approach, not as a standalone fix.

Frequently Asked Questions
Does GlucoTrust really work? The evidence is ingredient-specific. GlucoTrust’s strongest ingredients — Gymnema Sylvestre (400 mg), Chromium (200 mcg), and Licorice Root — have published research supporting blood sugar effects. Gymnema at 400 mg showed HbA1c reductions in a clinical study. However, Cinnamon at 200 mg is significantly underdosed compared to effective clinical ranges (1,000-6,000 mg/day). Individual response varies significantly based on baseline metabolic health, diet, and lifestyle.
How long does it take for GlucoTrust to show results? Based on the mechanism timelines of GlucoTrust’s key ingredients, a reasonable assessment window is 60–90 days. Gymnema Sylvestre shows sugar craving effects relatively quickly, but sustained glycemic benefit in trials emerged at 6–18 months. Chromium’s insulin cofactor effects build over weeks of consistent supplementation. If you don’t see any change by 60 days, the money-back guarantee allows a full refund.
What results can you realistically expect from GlucoTrust? Realistic expectations for non-diabetic adults with high-normal or prediabetic blood sugar: reduced sugar cravings (via Gymnema’s receptor-blocking effect on taste), modest fasting glucose improvement if chromium deficiency is a contributing factor, improved sleep quality from the sleep blend. GlucoTrust is unlikely to produce dramatic blood sugar normalization in isolation — dietary and lifestyle changes remain foundational.
Does GlucoTrust work better for some people than others? Yes. GlucoTrust is most likely to produce measurable results in adults with: high-normal fasting glucose (95–125 mg/dL), poor sleep quality that is contributing to insulin resistance, high sugar cravings, or sub-optimal Chromium status. It is least likely to produce results in people with well-controlled blood sugar through diet and lifestyle alone, or in people with advanced Type 2 diabetes requiring medication.
Is there clinical proof that GlucoTrust works? There is no GlucoTrust-specific clinical trial. The evidence base is for individual ingredients at various doses. Gymnema Sylvestre at 400 mg has a published 18-month randomized trial. Chromium at 200 mcg has a strong evidence base and an FDA-qualified health claim. The sleep ingredients have research supporting sleep quality improvement but not direct glucose effects. Cinnamon at 200 mg is underdosed versus the trials showing significant glucose effects.
Can I take GlucoTrust alongside prescription blood sugar medication? This requires a conversation with your prescribing physician before starting. Gymnema Sylvestre and Chromium can modestly lower blood sugar through independent mechanisms — in people already on glucose-lowering medications, additive effects are theoretically possible. Most physicians who are familiar with the evidence are comfortable with this combination, but the decision should be individualized based on your current medication regimen and baseline blood glucose.
Is GlucoTrust safe for long-term use? GlucoTrust’s ingredients are generally recognized as safe at the doses provided. Gymnema has been used in Ayurvedic practice for centuries. Chromium picolinate at 200 mcg is well below the observed safe level (1,000 mcg/day). The sleep herbs have established safety profiles at standard doses. As with any supplement, cycling (taking breaks) is reasonable for longer-term use. For the complete safety profile including potential interactions, see GlucoTrust Side Effects and Ingredients.
How does GlucoTrust for blood sugar compare to Gluco6? GlucoTrust and Gluco6 take different approaches to blood sugar support. GlucoTrust’s key differentiator is the sleep optimization blend — a mechanism that Gluco6 doesn’t prioritize. Gluco6 emphasizes its Sukre ingredient (a prebiotic fiber with emerging glucose-modulating evidence) and a different botanical lineup. For a detailed comparison, see Gluco6 Review 2026 to evaluate which formula’s approach matches your situation more closely.

Our Honest Verdict on Whether GlucoTrust Works
After evaluating the ingredient evidence, dosing, mechanism, and available user signal, here is my evidence-based assessment as a registered dietitian:
GlucoTrust is a formulaically coherent supplement with genuine evidence for its two strongest ingredients, a meaningful but underappreciated sleep mechanism, and at least one significant underdosing issue that honest reviewers should not paper over.
What makes me willing to say GlucoTrust is worth evaluating for the right candidate:
-
Gymnema Sylvestre at 400 mg is appropriately dosed and has published evidence for both the immediate (sugar craving reduction) and longer-term (HbA1c improvement in poorly controlled diabetics) effects that GlucoTrust is marketed on.
-
Chromium at 200 mcg has the strongest scientific foundation of any ingredient in the formula — an FDA-qualified health claim is not nothing. It represents a real, peer-reviewed evidence base.
-
The sleep-glucose connection is underappreciated and GlucoTrust specifically addresses it. If sleep quality is a contributing factor to your metabolic picture — and for many adults it is — this formula’s sleep blend offers a mechanism that is both evidence-based and rarely prioritized in competing blood sugar supplements.
-
The 60-day money-back guarantee is real. ClickBank’s refund policy is enforced at the platform level, not just promised by the vendor. You have two full months to evaluate whether the formula is doing anything for your situation before the refund window closes.
What concerns me about the formula:
-
Cinnamon at 200 mg is a significant underdosing problem. The published evidence for cinnamon’s glycemic effects is at 1,000–6,000 mg/day. GlucoTrust’s 200 mg is unlikely to contribute the blood sugar effects that cinnamon research supports. This is not a minor issue — it affects the credibility of the formula’s blood sugar mechanism stack.
-
No product-level RCT exists. This is standard for the supplement industry, but it means effectiveness claims are extrapolated from individual ingredient studies rather than tested in the specific combined formula.
My recommendation: If your situation fits the high-probability responder profile — high-normal fasting glucose, significant sugar cravings, poor sleep quality, or suspected chromium insufficiency — GlucoTrust is worth a 60–90 day trial, protected by the guarantee. Approach it as a support tool alongside dietary improvement, not as a standalone solution.
If you have diagnosed Type 2 diabetes, are already on medication, or have blood sugar symptoms that haven’t been clinically evaluated, the right first step is a conversation with your physician — not a supplement.
