HelloPharmacist Scorecard of Bitter Melon Complex 2500 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.

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 has a single active ingredient: bitter melon, supplied at 2,500 mg per capsule. Bitter melon is a tropical plant traditionally used in herbal medicine, though its effectiveness for specific health claims remains unproven by strong clinical evidence.

The capsule itself contains inactive ingredients—rice powder, gelatin, magnesium stearate, and silica—which are fillers and binders that help form and preserve the supplement.

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 glucose support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, glycemic control, 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 Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence we hold does not establish that bitter melon is effective for any of the conditions it's marketed for—including amenorrhea, athletic performance, liver disease, constipation, diabetes, or dyspepsia (stomach upset). The rating across all these uses is insufficient reliable evidence, meaning clinical trials haven't proven the benefit yet.

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 caveats. The most common side effects are gastrointestinal: heartburn, nausea, vomiting, diarrhea, constipation, flatulence, abdominal discomfort, headache, dizziness, and fatigue.

In clinical trials, these occurred in roughly 3% to 16% of people taking it. Rarely, it can cause low blood sugar (hypoglycemia) severe enough to bring on a coma or seizures in children.

One case report documented acute interstitial nephritis (kidney inflammation) after someone took high-dose bitter melon extract for several months; kidney function returned to normal after stopping it. For pregnancy, the safety data advises against use because seeds and high doses may cause uterine or other harmful effects.

For breastfeeding, there isn't enough reliable safety information, so it's best avoided. Talk with your doctor or pharmacist before use if you're pregnant, nursing, or have kidney disease.

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 your medications before starting this product if you take pazopanib (Votrient) for cancer or any antidiabetes drug—both carry a Moderate interaction risk. Also discuss it with your pharmacist if you take any P-glycoprotein substrate medications, which is a broad class.

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 Complex may be worth considering if you're interested in traditional herbal support, but the evidence for its specific uses is not yet established. If you take antidiabetes drugs, pazopanib, or any medications that depend on P-glycoprotein absorption, you'll need to check with your pharmacist first—the interaction risk is real.

Be ready for possible stomach upset, and watch for signs of low blood sugar if you're on diabetes medication.

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 Complex 2500 mg by Carlyle: Common Questions

Does Bitter Melon Complex 2500 mg by Carlyle interact with any medications?
Yes. Based on its ingredients, Bitter Melon Complex 2500 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 Complex 2500 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.
Will this lower my blood sugar if I take diabetes medication?
Bitter melon can lower blood glucose on its own, so yes—combining it with antidiabetes drugs raises the risk of low blood sugar (hypoglycemia). You'd need to monitor your blood sugar closely and talk with your doctor before adding this supplement if you're on diabetes medication.
What side effects should I expect?
Most side effects are stomach-related: heartburn, nausea, vomiting, diarrhea, constipation, gas, and abdominal discomfort. You might also feel headache, dizziness, or fatigue. In clinical trials, these occurred in about 3% to 16% of people taking bitter melon. Serious side effects like severe low blood sugar are rare.
Can I take this while pregnant or breastfeeding?
No—the safety data advises against bitter melon in pregnancy because seeds and high doses may cause uterine or other harmful effects. For breastfeeding, there isn't enough reliable safety information, so it's best avoided. Talk with your doctor if you're pregnant or nursing.
Does this supplement actually work for diabetes?
The evidence we hold does not establish that bitter melon is effective for diabetes. The rating is insufficient reliable evidence, meaning clinical trials haven't proven the benefit yet.
Is there anything else I should know before taking it?
One case report documented kidney inflammation after someone took high-dose bitter melon extract for several months. If you have kidney disease or take a cancer drug like pazopanib, talk with your pharmacist before starting this product.
