Whey is a substance produced during cheese production. It is the liquid content that remains after the milk has curdled and coagulated. Whey can be processed and isolated into three different types of protein: whey protein isolate, whey protein concentrate, and whey protein hydrolysate. This particular form of whey isolate is hydrolyzed, meaning that proteins are broken into small segments to promote rapid and easy digestion. Because of this, amino acid delivery into the bloodstream can be much faster than in typical whey protein. Hydrolyzed Whey Protein Isolate Powder is a rich source of protein that may support muscle growth and aid in the recovery of exhausted muscles after anaerobic exercise.* This protein powder is also a rich source of leucine and branched-chain amino acids (BCAAs), essential amino acids that are largely found in muscle tissues and used primarily in the production of proteins. The hydrolysis process may give this whey protein a bitter taste, which can be diluted by mixing it into smoothies. Our Hydrolyzed Whey Protein Isolate is unflavored, unsweetened and does not contain any fillers, additives and artificial flavors.
