5-HTP 用于 Appetite Control

C

Double-blind RCT (n=20) found 750 mg/day reduced caloric intake by 38% and produced greater weight loss (1.5 kg vs. +0.2 kg placebo) over 5 weeks. A 12-week crossover trial confirmed reduced carbohydrate and fat intake at 900 mg/day. Sample sizes are small but findings are mechanistically consistent.
