The essential amino acids include leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. Amino acids are the building blocks of protein. They are crucial for the synthesis of muscle growth, the prevention of muscle catabolism, and mental health.

Although the three Branch Chain Amino Acids (BCAAs) are more frequently associated with muscle gain and recovery, we recommend taking our Essentials EAAs if you are concerned that your diet is leaving you short.
