Whey protein is used as a bodybuilding supplement because it provides a high quantity of branched chain amino acids (BCAAs). The BCAAs, particularly leucine, trigger protein synthesis and provide energy to the muscles as they are being exercised. When it is taken during exercise, whey protein increases blood flow, and thus nutrients, to the muscles. After exercise, the use of whey protein may help increase muscle mass.
