WHAT IS WHEY PROTEIN ISOLATE?
Whey protein isolate (often whey isolate) is a dietary supplement and food ingredient created by separating components from milk. 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. The difference between the whey protein forms is the composition of the product, particularly the protein content.
Whey isolates contain the higher percentage of pure protein, 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.
Whey protein is popular among athletes today because of its ability to be digested very rapidly and help return the post-workout body back from a catabolic (muscle-wasting) state to an anabolic (muscle-building) state.
