Description
Isoleucine is one of the 20 amino acids that make up protein, and is one of the eight essential amino acids required by the human body. It belongs to the branched-chain amino acid. It works with valine and leucine to promote normal growth of the body, repair tissues, regulate blood sugar, and provide the necessary energy.
