FM Nutrition ISO-Generate 100% Whey Protein Isolate 2lb (92% Pure Protein)

There are numerous types of whey protein, with concentrate, isolate and hydrolysate being the three most common. Each carries varying rates of absorption, meaning, the body can only process a certain amount of the protein from each form. Whey concentrate carries the lowest absorption at approximately 70-80% with some inferior brands being even less. Isolate and hydrolysate carry absorption rates of 90-96% with hydrolysate being far more expensive and possessing no proven benefits over isolate in terms of absorption or digestion. This leaves isolate and concentrate to be the only two logical choices in whey protein, but concentrate will carry higher levels of fat and almost always much higher levels of lactose making it harder to digest, especially for those with any lactose intolerance.
