Whey protein is whey protein obtained from whey. Depending on the type of production, it is differentiated into whey protein concentrate, whey protein isolate, whey protein hydrolysate and clear whey protein isolate (clear whey). All whey proteins are characterised by a very high protein content and a high biological value due to their full amino acid profile including all essential (EAA) and branched-chain (BCAA) amino acids. The biological value indicates how well a dietary protein can be converted into the body's own protein.
Whey protein concentrate has a naturally higher fat and lactose (carbohydrate) content than whey protein isolate.
