 L-Leucine, commonly known as Leucine, is known as one of three branch-chain amino acids. Because it is an essential amino acid, humans cannot synthesize it. This means that it must be obtained through diet or supplements. Some of the foods that contain L-Leucine include eggs, fish, chicken, lentils,almonds and cashews, among others. amino acid
