HelloPharmacist Scorecard of Bitter Melon 1200 mg by Carlyle

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

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.
  • “Bitter Melon” is listed as a grouped ingredient — the label gives one combined amount (1,200 mg) without saying how much of each component you get.

This product contains one active ingredient: bitter melon fruit extract at 1200 mg per capsule. Bitter melon is a tropical plant traditionally used in herbal medicine; the extract concentrates its compounds into a convenient capsule form.

The remaining ingredients—rice powder, gelatin, magnesium stearate, and silica—are inactive excipients that help form and stabilize the capsule.

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 Bitter Melon's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Blood sugar and metabolic health support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Obesity, Glucose management, Insulin sensitivity.
  • The closest evidence on file: Bitter Melon is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Bitter Melon is rated "Insufficient Reliable Evidence To Rate" for Obesity, Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence we hold does not establish that bitter melon is effective for any condition. The available data rates its use for amenorrhea, athletic performance, liver disease, constipation, diabetes, and indigestion all as having insufficient reliable evidence.

This doesn't mean bitter melon doesn't work—only that the research backing its use for these purposes isn't yet strong enough to draw firm conclusions.

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 is generally well tolerated when taken by mouth, but it does come with cautions. The most common side effects are gastrointestinal: heartburn, nausea, vomiting, diarrhea, constipation, flatulence, and abdominal discomfort occurred in about 3% to 16% of people in studies.

You might also experience dizziness, fatigue, or headache. Rarely, very low blood sugar (hypoglycemia) and seizures (mainly in children) have been reported.

One case report documented a person who developed kidney inflammation after taking bitter melon extract at increasing doses (600 mg daily, then 1200 mg daily) over seven months; their kidney function recovered after stopping the supplement. Because of these safety concerns, traditional medicine advises against bitter melon in pregnancy—the seeds and high doses may cause harmful effects.

There isn't enough reliable data on safety during breastfeeding, so it's best avoided then too.

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.

Check with your pharmacist if you take diabetes or blood sugar medications (risk of low blood sugar), any P-glycoprotein substrate drugs (which may accumulate to higher levels), or pazopanib for cancer. These carry Moderate interaction severity and need dose or timing adjustments.

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.

Bitter melon may appeal to people interested in traditional herbal remedies, but the evidence for its effectiveness isn't yet established in our data. More importantly, if you take diabetes medications, P-glycoprotein substrate drugs (certain cancer treatments), or pazopanib, this product poses real interaction risks.

Talk with your pharmacist before starting—especially if you're pregnant, breastfeeding, or managing blood sugar.

Bitter Melon3 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 1200 mg by Carlyle: Common Questions

Does Bitter Melon 1200 mg by Carlyle interact with any medications?
Yes. Based on its ingredients, Bitter Melon 1200 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 1200 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 bitter melon if I'm pregnant or breastfeeding?
During pregnancy, traditional use suggests avoiding bitter melon—the seeds and high doses may cause unwanted effects. While breastfeeding, there isn't enough safety data, so it's best to avoid it. Talk with your doctor or pharmacist about your specific situation before starting.
What are the most common side effects?
The main side effects are digestive: heartburn, nausea, vomiting, diarrhea, constipation, gas, and belly discomfort. These occurred in about 3% to 16% of people in studies. You might also feel dizzy, tired, or get a headache.
Will bitter melon help my blood sugar or diabetes?
The evidence we hold rates bitter melon's use for diabetes as having insufficient reliable evidence—we can't yet say whether it works for that purpose. If you do take it with diabetes medications, there's a risk of your blood sugar dropping too low, so you'd need close monitoring.
What is bitter melon and why is it in supplements?
Bitter melon is a tropical plant traditionally used in herbal medicine. This product contains an extract—a concentrated form of the plant's active compounds—in capsule form for convenient dosing.
Is there anything else I should watch for?
One rare case report linked bitter melon to kidney inflammation after months of use. If you notice changes in how often you urinate, swelling, or fatigue, tell your doctor. Also, avoid bitter melon if you take pazopanib for cancer, because of a potential interaction.
