HelloPharmacist Scorecard of GTF Chromium by Innate Response Formulas

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 19 active ingredients.
  • “Chromium” is listed as a grouped ingredient — the label gives one combined amount (100 mcg) without saying how much of each component you get.
  • “Immune Blend” is a proprietary blend — the label gives one combined amount (206 mg) without saying how much of each component you get.
  • “Bioactive Enzymes & Proteins” is listed as a grouped ingredient — the label gives one combined amount (75 mg) without saying how much of each component you get.

GTF Chromium contains 19 ingredients total. The active ones include organic beet, broccoli, and parsley; brewer's yeast (S. cerevisiae, which appears twice in the formula); CoQ10 (coenzyme Q10); glutathione; beta-glucans; alpha-lipoic acid (also called lipoic acid); probiotics; and carrot.

There's also a chromium blend and blends labeled Immune Blend, Bioactive Enzymes & Proteins, and Organic Whole Food Blend. The inactive ingredients are vegetable cellulose, organic rice bran, vegetable lubricant, and silica.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Beta-glucans) (Natural Medicines).
  • On file: Coenzyme Q10 deficiency — rated "Likely Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Dyslipidemia — rated "Likely Effective" (Beta-glucans) (Natural Medicines).
  • On file: Antibiotic-associated diarrhea — rated "Possibly Effective" (Probiotics) (Natural Medicines).
  • On file: Athletic performance — rated "Possibly Effective" (Beet) (Natural Medicines).

The ingredients in this product have mixed evidence. Beet shows possibly effective evidence for athletic performance and exercise-induced muscle soreness.

Broccoli is possibly effective for colorectal cancer. Carrot is possibly effective for vitamin A deficiency.

Brewer's yeast is possibly effective for irritable bowel syndrome. CoQ10 is possibly effective for fibromyalgia, migraine headache, heart failure, and diabetic nerve pain — and likely effective for CoQ10 deficiency itself.

Alpha-lipoic acid is possibly effective for diabetic nerve pain, high cholesterol, and weight management. Beta-glucans are likely effective for high cholesterol and heart disease.

Probiotics are possibly effective for eczema, respiratory infections, antibiotic-related diarrhea, constipation, and other conditions. For parsley, glutathione, and several other ingredients, the evidence in our data is insufficient to rate their effectiveness.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 10 of the 10 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 10 of 10.
  • General safety write-ups exist for 10 of 10.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated when used short-term at typical doses. Beet and broccoli as foods are safe for most adults; concentrated supplements of either lack robust safety data.

Brewer's yeast commonly causes gas and flatulence; rarely, it may cause migraine or allergic reaction. CoQ10 generally causes no serious side effects, though gastrointestinal symptoms like nausea and diarrhea occur in less than 1% of users.

Alpha-lipoic acid may cause headache, nausea, or heartburn. Parsley is safe in food amounts but concentrated extracts and medicinal doses lack good safety data and carry rare risks of serious effects at very high doses.

Beta-glucans are well tolerated orally. Probiotics are generally safe in healthy people but should be used cautiously in seriously ill or immunocompromised individuals.

Glutathione's long-term oral safety is unclear, and inhaled forms can cause airway narrowing in people with asthma.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 8 of the 10 matched ingredients can interact with medications — Beet, Brewer's Yeast, Alpha-lipoic Acid, Parsley, Coenzyme Q10, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments; diabetes medications; lithium.
  • For scale: 1,358 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take any monoamine oxidase inhibitors (MAOIs) for depression — this is the most serious interaction. Also flag any blood pressure medications, blood thinners (especially warfarin), diabetes medications, thyroid hormones, diuretics, immunosuppressants, chemotherapy drugs, antibiotics, or antifungals.

The product contains ingredients that may affect how these drugs work.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

This is a multi-ingredient formula with a broad range of plant extracts and nutrients. It may appeal to people interested in whole-food-based chromium and immune support, but the number of active ingredients means multiple potential drug interactions — especially with blood pressure medications, blood thinners, diabetes drugs, and thyroid hormones.

Anyone taking prescription medications should check their exact list against the interactions on this page and discuss it with their doctor or pharmacist before starting. If you're pregnant or nursing, talk with your healthcare provider first, especially about parsley, lipoic acid, and glutathione, which have safety concerns during those times.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in GTF Chromium with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

organic Beet3 drug types · 861 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D
Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

Likelihood Possible Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Likelihood Possible Evidence D

organic Parsley8 drug types · 443 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, parsley might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Animal research suggests that parsley has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, parsley might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that parsley might decrease blood glucose. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, parsley might increase serum levels of CYP1A2 substrates.
Laboratory research suggests that parsley can inhibit CYP1A2.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, parsley might enhance or interfere with the effects of diuretic drugs.
Animal research suggests that parsley seed extract increases urine elimination. Parsley leaf and root might also interfere with diuretic therapy due their purported aquaretic effects.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, parsley might increase the duration of pentobarbital effects.
Animal research suggests that parsley juice prolongs the action of pentobarbital, perhaps by decreasing cytochrome P450 levels. It is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Theoretically, large quantities of parsley might increase sirolimus levels.
In one case report, an adult female with a history of kidney transplant presented with elevated blood sirolimus levels, approximately 4-7 times greater than previous measures, after daily consumption of a juice containing approximately 30 grams of parsley for 7 days. Sirolimus levels returned to normal a week after the parsley juice was discontinued.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, large amounts of parsley leaf and root might decrease the effects of warfarin.
Parlsey contains vitamin K.

Likelihood Possible Evidence D
Aspirin

Theoretically, aspirin might increase the severity of allergic reactions to parsley.
In one case, severe urticaria and swelling were reported after taking aspirin with parsley in an individual with a known mild parsley allergy.

Likelihood Unlikely Evidence D

Beta Glucans2 drug types · 293 drugs

Antihypertensive Drugs

Theoretically, taking beta-glucans with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that taking beta-glucans may reduce systolic and diastolic blood pressure in some hypertensive individuals.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, beta-glucans might interfere with immunosuppressive therapy.
Some clinical research shows that beta-glucans have immunostimulant effects.

Likelihood Possible Evidence D

Lipoic Acid5 drug types · 263 drugs

Alkylating Agents

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of alkylating agents.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy. Advise patients to consult their oncologist before using alpha-lipoic acid.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, alpha-lipoic acid may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro, alpha-lipoic acid inhibits platelet aggregation.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of antitumor antibiotics.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of antitumor antibiotic drugs, which work by generating free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using alpha-lipoic acid.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, alpha-lipoic acid might decrease the effects of thyroid hormone drugs.
Animal research suggests that co-administration of thyroxine with alpha-lipoic acid reduces conversion into the active T3 form.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking alpha-lipoic acid with antidiabetes drugs might increase the risk of hypoglycemia.
Although some small clinical studies have suggested that alpha-lipoic acid can lower blood glucose levels, larger clinical studies in patients with diabetes have shown no clinically meaningful effect. Additionally, co-administration of single doses of alpha-lipoic acid and glyburide or acarbose did not cause detectable drug interactions in healthy volunteers.

Likelihood Unlikely Evidence B

Probiotics2 drug types · 222 drugs

Antibiotic Drugs

Theoretically, taking antibiotic drugs with certain probiotics might decrease the effectiveness of probiotics.
Many probiotics are bacteria. Since these preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of sensitive organisms. Human research shows that taking probiotic concurrently with antibiotic treatment does not affect the diversity of the gut microbiome compared with antibiotic treatment in the absence of probiotics. Tell patients to separate administration of antibiotics and these preparations by at least two hours.

Likelihood Probable Evidence D
Antifungals

Theoretically, taking antifungals with certain probiotics might decrease the effectiveness of probiotics.
Some probiotics such as Saccharomyces boulardii are fungi. Therefore, simultaneously taking antifungals might kill a significant number of these organisms.

Likelihood Possible Evidence D

CoQ103 drug types · 198 drugs

Alkylating Agents

Coenzyme Q10 has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals.
Theoretically, antioxidants such as coenzyme Q10 might protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy. The clinical importance of this interaction is unknown.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Coenzyme Q10 is chemically similar to menaquinone and might have vitamin K-like procoagulant effects, which could decrease the effects of warfarin.
Concomitant use of coenzyme Q10 and warfarin might reduce the anticoagulant effects of warfarin. Four cases of decreased warfarin efficacy thought to be due to coenzyme Q10 have been reported. However, there is some preliminary clinical research that suggests coenzyme Q10 might not significantly decrease the effects of warfarin in patients who have a stable INR.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, coenzyme Q10 might have additive effects with antihypertensive drugs.
Some clinical research shows that coenzyme Q10 can significantly lower blood pressure, although other studies have shown conflicting results.

Likelihood Possible Evidence B

organic Broccoli2 drug types · 187 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B

Chromium5 drug types · 178 drugs

Antidiabetes Drugs

Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.

Likelihood Possible Evidence A
Insulin

Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,

Likelihood Possible Evidence B
Levothyroxine (Synthroid, Others)

Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.

Likelihood Probable Evidence B
Aspirin

Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.

Likelihood Possible Evidence D

S. cerevisiae4 drug types · 136 drugs

Monoamine Oxidase Inhibitors (Maois)

Theoretically, taking brewer's yeast with MAOIs might increase the risk of hypertension.
Brewer's yeast contains tyramine. Taking brewer's yeast with MAOIs might increase the risk for hypertensive crisis.

Likelihood Likely Evidence D
Antidiabetes Drugs

Taking brewer's yeast with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking chromium-containing brewer's yeast can decrease levels of blood glucose in diabetic patients being treated with antidiabetes drugs.

Likelihood Possible Evidence B
Lithium

Theoretically, taking brewer's yeast with lithium might cause additive effects and side effects.
Some brewer's yeast products contains lithium.

Likelihood Possible Evidence D
Antifungals

Theoretically, taking antifungals with some brewer's yeast products might decrease the effectiveness of brewer's yeast.
Some brewer's yeast products contain live yeast. Therefore, simultaneously taking antifungals might kill a significant number of the organisms.

GTF Chromium by Innate Response Formulas: Common Questions

Does GTF Chromium by Innate Response Formulas interact with any medications?
Yes. Based on its ingredients, GTF Chromium has a known interaction with 1,383 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
GTF Chromium contains 19 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant?
Several ingredients here have safety concerns in pregnancy. Parsley is rated likely unsafe. Glutathione and alpha-lipoic acid have insufficient data and are best avoided unless your doctor advises otherwise. Broccoli and carrot are likely safe, and probiotics are possibly safe. Talk with your doctor or pharmacist about your specific situation before starting.
What does the chromium in this product do?
The product facts we have don't specify what chromium is dosed for or what it does in this formula — the chromium is listed as a blend with components shown separately. If you'd like to know its intended role, check the product label or contact the manufacturer.
Will this give me red urine or stools?
Yes — beet is a common cause of red or dark-colored urine and stools when taken as a supplement. This is harmless and should resolve once you stop taking the product. In rare cases, people have reported black stools.
Is this safe if I have a weakened immune system?
Probiotics in this product may pose a risk if your immune system is severely compromised — there's concern they could cause infection in that situation. Brewer's yeast also may not be safe for people with weakened immunity. Talk with your doctor before using this product if your immune system is suppressed.
Can I take this with my blood thinner?
Not safely without checking first. This product contains parsley, CoQ10, lipoic acid, and probiotics — all of which have documented interactions with blood thinners. The risk ranges from potentially reduced effectiveness of your medication to increased bleeding. Your doctor or pharmacist needs to review your specific blood thinner and this product together.
What side effects might I notice?
Most common: gas, flatulence, and digestive upset from brewer's yeast or probiotics; headache or nausea from CoQ10 or lipoic acid; red stools from beet. Serious side effects are rare with normal use but can include allergic reactions (swelling, hives, anaphylaxis in sensitive people), especially from beet or parsley. Stop and seek help if you have trouble breathing or severe swelling.
