HelloPharmacist Scorecard of Bitter Melon 1000 mg by NusaPure

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 12, 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: bitter melon extract at 1000 mg per capsule. Bitter melon is a tropical plant used traditionally to support various health goals.

The capsule itself is filled with inactive ingredients—cellulose, silica, magnesium stearate, and rice powder—that serve as binders, flow agents, and fillers.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Bitter Melon product and its label doesn't state a use — see Bitter Melon's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

We don't have reliable evidence in our data to rate bitter melon for any of the uses it's promoted for—amenorrhea, athletic performance, liver disease, constipation, diabetes, or upset stomach. That doesn't mean it doesn't work; it means rigorous clinical trials haven't settled the question yet.

If you're thinking about using it for a specific health goal, that's a conversation to have with your pharmacist or doctor.

The evidence, ingredient by ingredient Bitter Melon

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.

Bitter melon taken orally is generally well tolerated, though gastrointestinal effects are common. In clinical studies, about 3% to 16% of people reported heartburn, nausea, vomiting, diarrhea, constipation, flatulence, or belly discomfort.

Rarely, it can cause dizziness, fatigue, or headache. One case report documented kidney inflammation after months of higher-dose bitter melon extract, which resolved after stopping it.

For pregnancy: the safety data advises against it—traditionally seeds and high doses have been avoided because they may trigger harmful effects. For breastfeeding: there isn't enough reliable safety information, so it's best to avoid it while nursing.

If you're pregnant or breastfeeding and interested in this product, talk with your pharmacist or doctor for personalized advice.

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 — Bitter Melon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 282 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 this, check whether you're on diabetes medications (insulin, metformin, sulfonylureas, and others)—bitter melon may lower your blood sugar too far. Also double-check if you take pazopanib or any P-glycoprotein substrates, a wide drug class that includes certain heart and antiviral medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Bitter melon works best for people without diabetes, not on cancer drugs, and without a long list of medications sensitive to absorption changes. If you take diabetes drugs, a blood thinner, heart medication, or an antiviral, check your exact medications here before you start.

Pregnant and breastfeeding folks should avoid it.

Bitter melon extract3 drug types · 282 drugs

Antidiabetes Drugs

Taking bitter melon with antidiabetes drugs might increase the risk of hypoglycemia.
Bitter melon can lower blood glucose levels and might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Theoretically, bitter melon might increase levels of P-glycoprotein substrates.
Bitter melon might inhibit the p-glycoprotein (P-gp) intestinal pump and increase intracellular levels of P-gp substrates. In vitro research in intestinal cells shows that 1-monopalmitin, a constituent of bitter melon, increases levels of daunomycin, a P-gp substrate. Additionally, drinking bitter melon juice has been associated with a case of acute pancreatitis in a patient who had been taking pazopanib, a P-gp substrate, for 8 years. Researchers theorize that inhibition of P-gp led to increased levels of pazopanib, resulting in pazopanib-induced pancreatitis.

Likelihood Possible Evidence D
Pazopanib (Votrient)

Theoretically, bitter melon might increase levels of pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 8 years for renal cell carcinoma experienced signs and symptoms consistent with acute pancreatitis 4 days after drinking bitter melon juice at a dose of 100-150 mL daily. The patient's symptoms, amylase levels, and lipase levels improved upon discontinuation of bitter melon and pazopanib. Pazopanib treatment was re-initiated with no further evidence of pancreatitis. Researchers theorize that inhibition of P-glycoprotein by bitter melon led to increased levels of pazopanib, a P-glycoprotein substrate, resulting in pazopanib-induced pancreatitis.

Bitter Melon 1000 mg by NusaPure: Common Questions

Does Bitter Melon 1000 mg by NusaPure interact with any medications?
Yes. Based on its ingredients, Bitter Melon 1000 mg has a known interaction with 282 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bitter Melon 1000 mg 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 this if I have diabetes or take diabetes medication?
You should talk with your doctor or pharmacist first. Bitter melon itself lowers blood sugar, so combining it with diabetes drugs raises your risk of low blood sugar (hypoglycemia). If your doctor clears it, you'd need to monitor your glucose closely and may need a dose adjustment.
What side effects should I expect?
The most common ones are gastrointestinal: heartburn, nausea, vomiting, diarrhea, constipation, or belly discomfort. These happened in about 3% to 16% of people in studies. Dizziness, fatigue, or headache can occur too. Serious effects are rare but have been reported.
Is there evidence this supplement actually works?
We don't have reliable evidence in our data to rate bitter melon for any specific use—whether that's blood sugar, digestion, athletic performance, or anything else. That means the clinical picture isn't settled yet, not that it definitely doesn't work.
Is it safe to take while I'm pregnant or breastfeeding?
For pregnancy, the safety data advises against it because seeds and high doses traditionally have been avoided due to concerns about harmful effects. For breastfeeding, there isn't enough reliable safety information. Talk with your pharmacist or doctor before using it in either situation.
Can this interact with my other medications?
Yes—bitter melon can interact with diabetes drugs, some cancer medications, and potentially with a broad class of drugs that rely on intestinal absorption. The safest move is to search your exact medication names in the tool on this page before you start.
What is bitter melon extract?
It's a concentrated form of bitter melon, a tropical plant. This product delivers 1000 mg per capsule. It's been used traditionally for various health purposes, though the evidence for specific uses isn't established yet.
