About Bitter Melon
Bitter melon contains at least three active compounds with glucose-lowering properties: charantin (steroidal saponin), polypeptide-p (plant insulin), and vicine. Used extensively in traditional medicine across Asia, Africa, and South America for blood sugar management. Multiple clinical trials support modest glucose-lowering effects. May cause GI discomfort; should not be used during pregnancy. No established RDA/UL.
What Bitter Melon supports
- Contains charantin and polypeptide-p, which mimic insulin activity
- Used across Asian, African, and South American traditional medicine
- Multiple active compounds target glucose metabolism through different pathways
- Whole-food source with additional micronutrient content
How much Bitter Melon to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
500–2000
mg
Most studies use 500–2000 mg/day of bitter melon extract. Traditional preparations use the whole fruit or juice. Standardized extracts concentrate the active charantin and polypeptide-p compounds.
Clinical evidence
Moderate clinical evidence. Multiple clinical trials show modest glucose-lowering effects, but study quality is mixed
