Whey protein concentrate;
Whey protein concentrate is widely considered a economical form of protein for the human body to digest and use. Whey protein concentrate is micro-filtered and not heat treated to produce 80% pure protein. This process ensures that the protein stays intact and as pure as it can be. Whey protein concentrate is rich in both BCAA's and Glutamine. This makes it the ideal protein to help build muscle size, definition and aid recovery. Whey Protein Concentrate is often regarded as the cheaper alternative.
Whey Protein Isolate:
While whey protein concentrate has a protein content of around 80%, the protein content of whey protein isolate is more like 90%. This is because whey protein isolate undergoes a process called Cross-Flow Micro-filtration. This separates the protein from fat, cholesterol and lactose meaning a purer protein as the end product.
Whey protein isolate is believed to have less fat, cholesterol, lactose, carbohydrates and calories than most other proteins on the market. It is therefore a common choice for those looking to maintain low levels of body fat but who still require the protein to help their muscles grow, repair and recover. Although whey protein concentrate is already considered low in lactose, whey protein isolate is considered even lower because of the additional manufacturing processes. Whey protein isolate is therefore often recommended for athletes who suffer from lactose intolerance.
