A diterpene compound isolated from the root of the plant Coleus forskohlii, traditionally used in Ayurvedic preparations.

Why it’s used

Taken mainly for weight management, marketed around effects on fat metabolism.

What the evidence says

Human trials are few and small, with inconsistent results on body weight and body composition; some show modest changes in lean mass without clear fat loss, others show no effect. The evidence behind the weight-loss claim is not strong.

Dose studied

250–500 mg — daily dose of 10% forskolin extract used in a 12-week trial in overweight men.

Context

A frequently cited small trial used a forskolin extract standardized to 10% forskolin, dosed at 250 mg taken twice daily, in overweight and obese men over 12 weeks.
