The isolate significantly reduces the fat and carbohydrate in the form of lactose contained in the whey by means of a series of filtrations. In this way, a complete protein is obtained whose biologically active components reinforce and improve various immune functions. Whey protein isolate generates more insulin, which makes it ideal to take after exercise as its absorption rate is increased. It contains a proportion of branched chain amino acids that could stimulate the initiation of muscle protein synthesis and the maintenance of muscle tissue, causing an anticatabolic effect. The benefits of whey isolate have been seen both before and after resistance exercise.
