HelloPharmacist Scorecard of Bitter Melon Gold 500 mg by NutriGold

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.
  • No proprietary blends here — you can verify the dose of every single component.

Bitter Melon Gold is a single-ingredient supplement: 500 mg of bitter melon extract per capsule. The extract comes from the bitter melon plant and is encased in a pullulan capsule with organic rice concentrate as an inactive ingredient.

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: supports pancreatic health and blood sugar metabolism.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Glucose 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 for bitter melon extract isn't established in our data. We hold insufficient reliable evidence to rate it for amenorrhea, athletic performance, liver disease, constipation, diabetes, or dyspepsia.

That doesn't mean it doesn't work—it means the clinical trials we have access to haven't yet provided solid proof either way. If you're considering it for a specific condition, talk with your pharmacist or doctor about whether the research supports its use for what you're after.

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 in supplement amounts, though gastrointestinal upset is common—heartburn, nausea, vomiting, diarrhea, constipation, flatulence, abdominal discomfort, headache, dizziness, and fatigue show up in clinical studies in about 3 to 16 percent of users. Rare serious effects include dangerously low blood sugar (hypoglycemic coma) and seizures in children.

One case report noted kidney function decline linked to high-dose bitter melon extract; kidney function recovered after stopping it. The safety data advises against bitter melon during pregnancy because seeds and high doses have traditionally been avoided due to concerns about uterine effects.

There isn't enough reliable safety information to know whether it's okay while breastfeeding, so it's best to avoid it then—talk with your pharmacist or doctor if you're nursing.

Side effects, ingredient by ingredient Bitter Melon

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.

Double-check this product if you take blood sugar-lowering drugs (antidiabetes medications)—it may increase your risk of low blood sugar. Also check it against any cancer medications, especially pazopanib, and any drugs that rely on intestinal absorption pumps (P-glycoprotein substrates).

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 blood sugar medication, cancer drugs, or medications your gut absorbs carefully, check with your pharmacist before starting this. Bitter melon is generally tolerable as a supplement, but stomach upset is common and blood sugar concerns are real.

It's not recommended in pregnancy or while breastfeeding.

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 Gold 500 mg by NutriGold: Common Questions

Does Bitter Melon Gold 500 mg by NutriGold interact with any medications?
Yes. Based on its ingredients, Bitter Melon Gold 500 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 Gold 500 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 Gold if I'm taking diabetes medication?
No—not without your doctor or pharmacist checking first. Bitter melon lowers blood glucose on its own, and combining it with diabetes drugs raises the risk of blood sugar dropping too low. If you're on diabetes medication, talk with your pharmacist before starting this.
What are the most common side effects?
Stomach upset is the main one: heartburn, nausea, vomiting, diarrhea, constipation, gas, and abdominal discomfort happen in about 3 to 16 percent of people taking bitter melon. You might also notice headache, dizziness, or fatigue.
Is it safe to take while I'm pregnant?
No. The safety data advises against bitter melon during pregnancy because seeds and high doses have traditionally been avoided due to concerns about effects on the uterus and other harm. Talk with your doctor if you're pregnant and considering any supplement.
Can I take it while breastfeeding?
There isn't enough reliable safety information to know whether bitter melon is okay while nursing, so it's best to avoid it. Chat with your pharmacist or doctor if you're breastfeeding and want to use a supplement.
Does bitter melon extract actually work for diabetes?
The evidence isn't established in our data. We don't have enough reliable research to say whether it works for blood sugar control. If you're interested in it for diabetes, ask your doctor or pharmacist what the current evidence shows.
What's in this capsule besides the bitter melon extract?
The capsule itself is made of pullulan, and there's organic rice concentrate as a filler. Those are inactive ingredients—the active part is the 500 mg of bitter melon extract.
