L-Leucine is an essential amino acid, specifically classified as a “branched-chain amino acid” (BCAA). BCAAs, especially leucine, stimulate muscle protein synthesis and may be the major fuel involved in muscle-building reactions. This makes them especially important for body builders and other athletes in sports that demand explosive strength.
