Hypoglycemic efficacy and safety of Momordica charantia (bitter melon) in patients with type 2 diabetes mellitus.
Kim, Jung, Jung, et al. Complementary therapies in medicine, 2020.
Study design: Placebo-controlled randomized trial in people with type 2 diabetes using bitter melon extract as add-on therapy, ninety participants analyzed, for 12 weeks.
- Fasting blood glucose in the bitter melon extract group fell significantly (p = 0.014).
- HbA1c levels did not change, in either the bitter melon or placebo group.
- There were no serious side effects during the study period.
What it means for your product: The only reasonably clear positive signal, but the unchanged HbA1c shows the effect is limited. Use it as educational material, not a claim.
