Summary
The purpose of this investigation was to compare supplementation with 5-HTP to placebo on indices of body composition. A randomized trial compared a sample of 48 resistance-trained individuals taking either 100 mg of 5-hydroxytryptophan supplementation or a placebo.
The investigators tested anthropometric measurements using a multi-frequency bioelectrical impedance device (InBody® 270). The primary outcome (i.e., changes in anthropometric measurements) was assessed at the first visit (pre-test-) and post-test (8 weeks). Secondary outcomes include resting heart rate, blood pressure, and dietary intake.
