In another open-field, 12-week study, ForsLean® (10% diterpene forskolin) was evaluated in overweight volunteers for effect on body composition. ForsLean® was administered in a dose of 125 mg twice a day. Body composition measurements were taken on day 0, first month, second month and third month.

At the end of the study, it was observed that supplementation of ForsLean® resulted in significant decrease in total body weight (p<0.05), body fat (p<0.01), and improved BMI and lean body mass (p<0.05 both) compared to baseline. Overall, results indicated that supplementation of ForsLean® could be useful in weight loss management with no apparent subjective and objective side effects of the regimen.
