Branched-Chain Amino Acids.

Branched-chain amino acids (BCAAs) comprise leucine, isoleucine, and valine—three essential amino acids that bypass hepatic metabolism and directly enter muscle tissue. These compounds play a critical role in muscle protein synthesis, making them particularly valuable for athletes and individuals engaged in resistance training. BCAAs help minimize muscle breakdown during intense exercise and support recovery by facilitating amino acid availability when dietary protein intake may be insufficient. Their unique metabolic pathway makes them distinct from other amino acids, offering targeted support for lean muscle maintenance and performance optimization.
