HelloPharmacist Scorecard of Gymnema Leaves Powder 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 product contains one active ingredient: Gymnema sylvestre powder. Gymnema is a plant traditionally used in Ayurvedic medicine, and this supplement delivers it as a fine powder with no other inactive ingredients listed.

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: Supports normal blood sugar levels.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Glucose metabolism, Glycemic control.
  • 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's effectiveness is not established in the data we hold. For diabetes, obesity, prediabetes (impaired glucose tolerance), and metabolic syndrome — all conditions this herb is marketed for — the ratings are insufficient reliable evidence.

That doesn't mean it doesn't work; it means the studies we have aren't conclusive enough to rate it one way or the other.

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 in the short term, but quality varies between products, so you're betting partly on manufacturer standards. The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know if it's safe for you or your baby.

One rare but serious case of drug-induced hepatitis (liver inflammation) with jaundice and weakness was reported in someone who drank gymnema tea three times daily for 10 days; another case linked it to a blood disorder. These are uncommon, but they signal your liver can react to it.

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.

Check with your pharmacist if you take antidiabetes drugs (blood sugar medicine) — the biggest risk is low blood sugar. Also flag any medications metabolized by CYP1A2 or CYP2C9 enzymes; gymnema can raise or unpredictably change their levels.

If you take tolbutamide (Orinase) specifically, gymnema may reduce how well it works. Worst case, run any prescription you're on through the checker below before you add this supplement.

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.

If you take a diabetes medication or any prescription drug metabolized by your liver, you need to check this with your pharmacist before starting. Gymnema lowers blood sugar and can interact with how your body processes many common medications.

If you're pregnant, breastfeeding, or have liver concerns, talk with your doctor or pharmacist first — the safety data doesn't support use in those situations.

Gymnema sylvestre, Powder6 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 Leaves Powder by Bixa Botanical: Common Questions

Does Gymnema Leaves Powder by Bixa Botanical interact with any medications?
Yes. Based on its ingredients, Gymnema Leaves Powder 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 Leaves Powder 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.
Will gymnema actually help my blood sugar or weight?
The evidence in our data is insufficient to say reliably. Studies on gymnema for diabetes, prediabetes, obesity, and metabolic syndrome haven't been conclusive enough for us to rate it effective or ineffective — so we honestly don't know if it'll help you based on the research we hold.
Is it safe if I'm pregnant or breastfeeding?
No — the safety data advises against it in both cases because there isn't enough information to know if it's safe for you or your baby. Talk with your doctor or midwife before taking it.
What are the side effects?
Short-term, gymnema is generally well tolerated. A rare but serious case of liver inflammation (hepatitis) with weakness, jaundice, and blood cell problems has been reported, so if you notice yellowing of skin or eyes, unusual fatigue, or bruising, stop and see your doctor right away.
Why does this interact with so many drugs?
Gymnema affects enzymes in your liver that break down a wide range of medications — it can speed some up or slow others down. That's why we list 840 individual drugs affected across its enzyme interactions, even though you probably only take a handful of them.
Does this product have fillers or other ingredients?
No — this is pure Gymnema sylvestre powder with no inactive ingredients listed.
