Branched-chain amino acids, more commonly known as BCAAs, include the essential amino acids leucine, isoleucine, and valine.

BCAAs differ from other amino acids because they have a branched structure and are the only amino acids that are broken down in skeletal muscle. They’re considered essential because you must consume them through your diet (1).

Athletes and gym-goers commonly take BCAA supplements to enhance performance, reduce soreness, and prevent muscle fatigue (1).
