One of your best choices would be Dymatize Elite Whey Protein. This instantized protein powder is a blend of whey protein concentrates, whey protein isolates, and whey peptides. There"s no added sugar, fat, fructose, salt, or carbohydrates. Since some people have trouble digesting large servings of protein, even very easy-to-digest protein like whey, Dymatize adds the Zytrix® digestive enzyme blend to help improve absorption. Elite Whey Protein comes in some great flavors with more to chose from than the usual Vanilla, Chocolate and Strawberry.
