Taking 5-HTP as a supplement increases the production of serotonin. Serotonin in the hypothalamus is thought to be involved in regulating food intake, promoting within-meal satiation, and improving post-meal satiety. Preliminary evidence suggest that taking 5-HTP orally, 300 mg three times daily 30 minutes before meals for 2 to 12 weeks improves early satiety and decreases daily caloric intake in obese women. In a randomized, double blind placebo controlled clinical trial, C.fimbriata extract and placebo were orally administered as 500 mg capsules twice daily (1 g/day) and dietary intake and exercise were monitored weekly. The results measured a decline in waist circumference by 5.7 cm, compared to only 2.8 cm loss in the placebo group.
