Amino acid gels may help preserve muscle in aging
NCT ID NCT07754760
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This trial tests whether taking an essential amino acid supplement with a standard-protein breakfast increases the amount of amino acids in the blood of healthy adults aged 60 and older. Participants receive either an amino acid gel or a placebo on separate occasions, and blood samples are taken to measure amino acid levels. The goal is to find which amino acid mix works best to support muscle protein synthesis, which could help prevent age-related muscle loss.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Essential amino acid supplement
- What this could lead to
- If successful, this could help develop simple dietary strategies to preserve muscle mass and function in older adults, potentially reducing the risk of sarcopenia.
- What could go wrong
- This is a small, early-stage trial with only 10 participants, so results may not apply broadly. The study measures blood amino acid levels, not actual muscle outcomes, so benefits remain uncertain.
