Exploring the effects of branched chain amino acids on sleep in veterans

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the potential benefits of dietary supplementation with branched chain amino acids (BCAAs) on sleep quality and cognitive function in veterans with traumatic brain injury. Participants will be randomly assigned to receive either BCAAs, rice protein, or a placebo for 21 days, with assessments conducted before and after the intervention. The study aims to determine the feasibility of BCAA supplementation in improving sleep-wake patterns and cognitive function in this population. Various measures, including self-report questionnaires and cognitive tests, will be utilized to evaluate outcomes.
