Purity is power. Isopure Protein has 50 grams of 100% pure whey protein isolate with zero carbs. And it's still packed with glutamine and nutrients, but no lactose or impurities so it's easy to drink, and goes down easy. The microfiltration process used to create Isopure Protein is so complete, we end up with the only completely clear milk protein when it is dissolved in water. Now that's what we call some seriously fine fuel.
