Whey protein concentrate

Whey protein is the protein contained in whey, the watery portion of milk that separates from the curds when making cheese.
Whey protein is used for improving athletic performance, as a food supplement, as an alternative to milk for people with lactose intolerance, for replacing or supplementing milk-based infant formulas, and for reversing weight loss and increasing glutathione (GSH) in people with HIV disease.
