Whey Isolate is made from Ultra-Filtered Whey Isolate that is extremely low fat and lactose and contains both Papain and Protease for protein absorption, and no cheap ingredients, like Glycine or Taurine, to increase protein levels. It is absorbed immediately, flooding your muscles with key amino acids. This makes Whey Isolate the perfect protein to take immediately after your workout, when your muscles crave protein the most.
