Of those nine, three are branch-chain amino acids (BCAAs). Leucine falls into both groups. All BCAAS are vital for building and repairing muscles, and some researchers say leucine may be the most ...

A multi-omics study reveals that impaired branched-chain amino acid (BCAA) catabolism is a key driver of sarcopenia, suggesting it as a potential therapeutic target.
