BCAA's are an important part of your daily nutrition and bodybuilding. The branched-chain amino acids are leucine, isoleucine, and valine. BCAAs are considered
essential amino acids because human beings cannot survive unless these amino acids are present in the diet. They are used by the body for many different functions, including muscle repair, nitrogen retention, glycogen uptake, etc etc... believe me, they are important, and if you look at any quality
whey protein, BCAA's are included (and their amounts usually listed) on the back of the container or package.
