Essential amino acids cannot be made by the body but are essential to protein metabolism.These amino acids must be acquired from food. Non-essential amino acids are required for normal cell functioning and can be synthesized from other amino acids in the body.thletes may supplement their diets with protein sources such as egg white powder, whey, casein or soy.
