Now Whey Protein Hydrolysate is a high quality protein that is enzymatically hydrolyzed (partially predigested) into smaller peptides for increased bioavailability and absorption compared to other whole proteins. In addition, this protein hydrolysate powder is instantized for easy mixability and dispersion. NOW Whey Protein Hydrolysate also has naturally occurring Branched Chain Amino Acids (BCAA's), and is deal for active individuals.Whey protein is considered to have the highest Biological Value of any protein source-superior in essential amino acid content to beef, milk, casein or soy.Typical Amino Acid ProfileEssential Amino Acids 42gL-Isoleucine 1200L-Leucine 2250L-Lysine 1800L-Methionine 425L-Phenylalanine 650L-Threonine 1250L-Tryptophan 325L-Valine 1125Non-Essential Amino AcidsL-Alanine 900L-Arginine 625L-Aspartic Acid 2150L-Cysteine 425L-Glutamic Acid 3350Glycine-375L-Histidine 375L-Proline 1425L-Serine 1200L-Tyrosine 575
