A human trial of Bitter Gourd extract against the standard modern medicine for diabetes - Metformin,
showed that Bitter Gourd use was INFERIOR to Metformin.

Bitter gourd extracts or juice ARE NOT approved or recommended as a treatment or for prevention of diabetes
by any national or international Endocrinology or Diabetes societies
due to low level, very weak foundational evidence that it can manage blood sugar +

There’s no medically approved form or formulation of bitter gourd that can be consumed SAFELY and EFFECTIVELY as a treatment for diabetes currently
The available studies are flawed by small sample size, lack of control and poor study design +

Bitter melon may be eaten as part of a healthy diet,
however,
consuming bitter melon beyond your dietary needs may lead to ill-health
You want to be a guinea pig?
Be my guest.
Maybe they'll name a new toxicity syndrome after you.
Congratulations.
End.
