This study is looking into whether a dietary supplement called Branched Chain Amino Acids (BCAA) could help improve sleep and thinking skills in Veterans who have sleep problems, possibly related to a traumatic brain injury. You would be given either BCAA, rice protein, or microcrystalline cellulose (placebo) to drink twice a day for 21 days. Researchers want to see if it's practical to run a larger study like this, how many people join and stick with it, and if the process is acceptable to participants. This study is currently recruiting and aims to enroll 300 participants. To join, you must be a Veteran, speak English, have sleep problems, and be between 18 and 89 years old.

Study design

This is an interventional study planning to enroll 300 participants. Participants will be randomly assigned to one of three groups in a double-blind fashion (meaning neither you nor the researchers will know which product you are receiving).

What's involved

You would consume a study product mixed in water twice daily for 21 days. Before and after this period, you will complete questionnaires, wear a wrist device to track activity, undergo pressure pain testing, and have your cognitive function assessed.

Compensation

Not stated in the trial record.

Follow-up

Assessments will be conducted at 5 weeks, which includes measuring recruitment, retention, adherence, and acceptability.
