NCT03990909

Brief Summary

Individuals will be recruited from the VA Portland Health Care System and the community affiliated with Oregon Health \& Science University. Traumatic brain injury status will be assessed as a contributing factor. Subjects will be randomized to one of 3 groups (BCAA or one of 2 placebo conditions) and instructed to consume study product twice daily for 21 days. Self-report questionnaires, wrist actigraphy, pressure pain testing, and cognitive function will be assessed pre and post the experimental period.
