leucine
Essential amino acid
Leucine is one of the essential amino acids—building blocks of protein that the body cannot synthesize and must obtain from food.
It plays a key role in muscle protein synthesis and is abundant in meat, dairy, and legumes.
Athletes and bodybuilders often supplement with leucine or branched-chain amino acids (BCAAs) to support muscle growth and recovery.
