About Whey Protein

Whey proteins are high quality proteins naturally found in cow’s milk.  Milk contains two major proteins: casein and whey.  Whey proteins comprise about 20% of the total milk protein.  Whey protein is more soluble than casein and has a higher protein quality rating.  Whey proteins are complete proteins containing all of the essential and non-essential amino acids needed by the body.  Whey proteins are also a rich source of the branched chain amino acids, leucine, isoleucine and valine.
