TNT MERCURY 100% PRIME WHEY is a “complete protein” that is fast and easy to digest. Whenever we eat a protein source, our body uses the 20 amino acids (which are the individual components of “protein”) to repair our bones, muscles, organs and virtually every body part and tissue in the human body. When a source of protein has all 9 essential amino acids, which are amino acids your body needs to get from food, that food is said to be a complete protein. Whey protein is high in Branched-Chain Amino Acids (BCAAs), which are 3 of the 9 essential amino acids that are of special importance for muscle repair and preservation. During both exercise and recovery, your body will break down a small amount of amino acids for fuel (1-5%) and the specific amino acids your body uses are the BCAAs.
