True Nutrition's Hydrolyzed Whey Protein High Grade is a high quality protein produced by a controlled enzyme treatment of whey protein, which provides amino acids, peptides, and polypeptides. The whey protein base material is highly nutritious. Since the enzyme treatment is a mild and carefully monitored process, the essential amino acids remain intact and the protein retains its high nutritional quality. The Hydrolyzed Whey Protein has undergone 7% total hydrolysis for a high concentration of di- and tri-peptides. As a result, this material will be bitter.
