IsoWhey is made with a pharmaceutical-grade blend of Isolated and Hydrolyzed Whey Protein Powders that are combined with a high potent digestive enzyme. IsoWell is produced from pasteurized whey that has non-protein elements removed. Once a sufficient amount of non-protein components are removed, the resulting protein material is dried. It is clean and flavorless, according to the American Dairy Products Institute. This is a verified and trusted source of protein. Whey protein isolate is a complete protein, which means it has all of the amino acids that are needed in a daily diet. It contains high levels of branched-chain amino acids. Branched-chain amino acids are unlike other amino acids in that they promote muscle growth by metabolizing directly into muscle tissue. Whey protein isolate contains a high level of leucine, which promotes the synthesis of muscle protein and muscle growth. It also promotes the loss of fat tissue because of the energy the body needs to process leucine. When compared with soy protein isolate, whey protein isolate has 50 percent more leucine.
