Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: break down food; grow and repair body tissue.
Essential amino acids cannot be made by the body and must come from food.
Nonessential amino acids can be produced by the body.
Amino acids are available as single ingredient, complexes or BCAA (Branch Chain Amino Acids)
