Bitter Melon (Momordica charantia)
Contains charantin and polypeptide-p with insulin-mimicking activity — lowers blood glucose through multiple mechanisms.
Bitter Melon (Momordica charantia) is a tropical fruit that has been used in traditional medicine across Asia, Africa, and the Caribbean for diabetes and blood sugar management. It contains several compounds with hypoglycemic properties including charantin, polypeptide-p (plant insulin), and vicine. These work through multiple mechanisms to lower blood glucose. While evidence is promising, more large-scale clinical trials are needed.
Increases cellular glucose uptake
Activates metabolic master switch
Decreases liver glucose production

Take with food
| Form | Type |
|---|---|
| 💊Standardized extract capsules | Recommended |
| 💊Fresh bitter melon juice | Alternative |
| 🧪Dried fruit powder | Alternative |
| 💊Whole fruit (food) | Alternative |
Capsules are preferred to avoid the intensely bitter taste. Juice is traditional but very unpalatable for most. Standardization varies.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Taking before meals may help with postprandial glucose. Capsules avoid the extremely bitter taste.
Reduced fasting glucose and HbA1c
Improved insulin response
