A whey protein isolate (often whey isolate) is a dietary supplement created by filtering milk protein. Whey is a by-product of the cheese-making process. Whey can be processed to yield whey protein in three forms: whey isolate, whey concentrate, or whey hydrolysate. Whey proteins are highly bioavailable, are very quickly absorbed into the body, and have a high concentration of branched-chain amino acids (BCAAs) which are highly concentrated in muscle tissue, and are used to fuel working muscles and stimulate protein synthesis. The difference between the whey protein forms is the process used to filter the proteins. Whey isolates yield a higher percentage of pure protein and can be filtered enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free.
