The Effects of a Pre-workout Supplement on Measures of Alertness, Mood, and Lower-Extremity Power.

Objective The purpose of this study was to investigate the effects of a multi-ingredient pre-workout supplement (MIPS) on mental and physical performance. Materials and methods Fourteen exercise-trained men (n=7) and women (n=7) completed this randomized, placebo-controlled, double-blind, counterbalanced, crossover trial. Participants consumed either a MIPS or a placebo in a randomized, counterbalanced order.

The Effects of 5-HTP on Body Composition: An 8-Week Preliminary RCT.

The purpose of this investigation was to determine the effects of supplementing with 100 mg daily of 5-Hydroxytryptophan (5-HTP) on indices of body composition in exercise-trained men and women. Sixty-one subjects volunteered for this investigation. Forty-eight subjects were randomized into a treatment ( = 31, 12 male/19 female; 100 mg 5-HTP daily; CLEANMOOD) or a placebo ( = 17, six male/11 female; maltodextrin).
