Whey protein originates from milk. It helps to digest rapidly and is safe for people who can’t tolerate lactose. Further processing of whey protein concentrate leads in pure whey protein isolate, with a reduced fat and lactose content and more highly bioavailable protein.
One of the best proteins for gaining muscle and losing fat is whey protein isolate. About 90–95 percent of the weight of it is protein in its raw form. Whey protein isolate is used by athletes and bodybuilders who want to shed pounds and become ripped because of its fat free and carbohydrate content.
