Iso Whey ZERO is made with the purest cross-flow micro filtered whey protein isolate (WPI) possible, while it truly contains ZERO lactose, ZERO trans fat and ZERO sugar. Protein is an essential building block of our body, a source of nutrients made up from amino acids produced by our body and supplemented from external sources. It contributes to maintaining and growing muscle tissues. You need more protein if you regularly do sports, if you want to increase your muscle mass, if you want to lose weight or as you get older. Iso Whey ZERO is perfect for athletes who aim for ultra-lean muscle gains as proteins contribute to muscle mass growth and muscle maintenance.
