EAS BCAAs contain the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine. BCAAs are considered essential amino acids because human beings cannot survive unless these amino acids are present in the diet. BCAAs are needed for the maintenance of muscle tissue and appear to preserve muscle stores of glycogen (a storage form of carbohydrate that can be converted into energy). BCAAs alsomay help prevent muscle protein breakdown during exercise.
