Essential Amino Acids - EAA

Essential amino acids are the amino acids that the human body cannot synthesise on its own, so they must be obtained through the diet or supplements. These amino acids are essential for many physiological processes, including protein synthesis, muscle growth and immune function. The essential amino acids are phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, histidine, leucine and lysine. Supplementing your diet with essential amino acids can be particularly important for athletes and for people following restrictive or vegetarian diets.
