What is Whey Protein Isolate?
Whey protein isolates are the highest quality whey proteins and are used to build very lean muscle mass. Isolates are filtered and processed to remove the fat and lactose and are 90%+ protein by weight. Whey protein is derived from milk and is the fastest-absorbing protein.
Whey protein isolate shakes typically have zero fat and zero carbs and are great if you are on a fat-loss diet. This product category only contains products that are pure whey protein isolates - no concentrates in here! If you are lactose intolerant or other proteins give you gas, you need one of these products.
While isolate shakes are typically a bit more costly than their whey protein concentrate counterparts, we believe that this is worth the money if you are on a fat-cutting diet, Atkins diet (or any other low-carb diet), or cannot eat lactose.
