HelloPharmacist Scorecard of Gymnema by Bixa Botanical

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.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This capsule contains one active ingredient: gymnema sylvestre extract. Gymnema is a plant used traditionally to support blood sugar balance, though the evidence for it isn't well established yet in the research we have.

The capsule itself is made from HPMC, a plant-based capsule material.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Gymnema's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: sugar metabolism support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, blood sugar control, glucose regulation.
  • The closest evidence on file: Gymnema is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Gymnema is rated "Insufficient Reliable Evidence To Rate" for Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence for gymnema isn't reliable enough to rate right now. We don't have sufficient data to say whether it actually works for diabetes, prediabetes, metabolic syndrome, or weight management.

Animal and some human studies suggest it may affect blood sugar, but more rigorous human research is needed before we can call it effective for any of these uses.

The evidence, ingredient by ingredient Gymnema

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Gymnema is generally well tolerated short-term, but quality varies between products, so you're not guaranteed consistency from one brand to the next. One rare case of drug-induced liver inflammation has been reported — a person who drank gymnema tea heavily for 10 days developed hepatitis, though they eventually recovered after treatment.

Do not use gymnema during pregnancy or while breastfeeding. There isn't enough safety data to know whether it's safe for you or your baby in either situation — talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or nursing.

Side effects, ingredient by ingredient Gymnema

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Gymnema.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 852 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 you take gymnema, check with your doctor or pharmacist if you take any diabetes or blood sugar medication — the biggest risk is dangerously low blood sugar. Also double-check if you take drugs metabolized by CYP1A2, CYP2C9, or CYP3A4 enzymes (a large group that includes many pain relievers, heart medications, and others).

Use our medication search tool to find your exact prescriptions.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Gymnema may interest you if you're exploring traditional plant remedies for blood sugar support, but know that the evidence for it isn't strong and it carries real interaction risks — especially if you take diabetes medications or drugs processed through certain liver enzymes. If you're on any prescription medication, check it against our tool before you start, and talk with your doctor or pharmacist first.

The risk of low blood sugar when combined with diabetes drugs is a serious concern.

Gymnema sylvestre extract6 drug types · 851 drugs

Antidiabetes Drugs

Theoretically, taking gymnema with antidiabetes drugs might increase the risk of hypoglycemia.
Gymnema reduces blood glucose levels in some human and animal research. In human studies, it has been shown to enhance the blood glucose lowering effects of hypoglycemic drugs. However, other research in adults with prediabetes or metabolic syndrome suggests that gymnema does not reduce fasting levels of blood glucose. Until more is known, monitor blood glucose levels closely.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP1A2.
Animal and in vitro research shows that gymnema can inhibit the CYP1A2 enzyme. In one animal study, oral administration of gymnema for 7 days increased the plasma concentrations of phenacetin, a CYP1A2 substrate, by about 1.4-fold and reduced the clearance of phenacetin by about 29%.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9.
Animal research shows that gymnema can induce the CYP2C9 enzyme. In one animal study, gymnema caused a 2.4-fold increase in the clearance of tolbutamide, a CYP2C9 substrate, in rats. In vitro research also shows that gymnema can inhibit CYP2C9.

Likelihood Possible Evidence D
Phenacetin

Theoretically, taking gymnema with phenacetin might increase the levels of phenacetin.
Animal research shows that gymnema, administered orally for 7 days, decreases the clearance of phenacetin in a dose-dependent manner by about 21% to 29% and increases plasma levels about 1.3- to 1.4-fold when compared to control.

Likelihood Possible Evidence D
Tolbutamide (Orinase)

Theoretically, taking gymnema with tolbutamide might the decrease levels of tolbutamide.
Animal research shows that gymnema, administered orally for 7 days, increases the clearance of tolbutamide by 2.4-fold when compared to control.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP3A4.
One in vitro study using rat liver microsomes shows that gymnema can modestly inhibit the CYP3A4 enzyme. However, other in vitro research using human liver microsomes shows that gymnema does not affect CYP3A4 activity. Animal research also shows that gymnema does not alter the function of CYP3A4. In one study in rats, oral administration of gymnema for 7 days did not alter the clearance of amlodipine, a CYP3A4 substrate.

Gymnema by Bixa Botanical: Common Questions

Does Gymnema by Bixa Botanical interact with any medications?
Yes. Based on its ingredients, Gymnema has a known interaction with 851 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Gymnema contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 gymnema if I'm on a diabetes medication?
Not without talking to your doctor first. Gymnema lowers blood sugar on its own, and animal research shows it makes diabetes medications work even stronger — which could cause your blood sugar to drop dangerously low. Your doctor may need to adjust your dose or monitor you closely.
Is gymnema safe to use while pregnant or breastfeeding?
No. There isn't enough safety data to know whether gymnema is safe for you or your baby during pregnancy or while nursing. You should avoid it during both. Talk with your doctor or pharmacist if you're considering it and are pregnant, planning to become pregnant, or breastfeeding.
Does gymnema actually work for blood sugar control?
We don't have enough reliable evidence to say. While some animal and human studies suggest it may affect blood sugar, the research isn't solid enough yet for us to call it effective. More rigorous studies are needed.
Has gymnema caused any serious side effects?
One rare case of drug-induced liver inflammation has been reported in someone who drank gymnema tea very heavily — three times a day for 10 days. The person recovered after treatment, but it shows that the liver can be affected in unusual circumstances.
How many active ingredients are in this product?
Just one: gymnema sylvestre extract. The rest of the capsule is the plant-based shell (HPMC), which is an inactive ingredient.
Can I trust that all gymnema products are the same quality?
No. Quality varies between products, so you may not get the same potency or purity from one brand to another. That's another reason to talk with your pharmacist about which product to choose.
