Common Types Of Whey Protein

The most common type of protein powders came from processed whey, which breaks down further into concentrate and isolate types. Whey is a common source of protein because it's derived from processing milk to make cheese. In concentrate form, whey is less expensive to produce and easier to find in health supplement stores.
Whey is one of the two major proteins found in milk (casein is the other) and is isolated from milk as a by product in the production of cheese and casein. Pure whey contains a large amount of the milk sugar lactose, as well as a variety of proteins, fat and cholesterol.

Whey Protein Concentrate: It contains about 80% pure protein. It is cheaper than isolate and contains slightly higher levels of calories, lactose and fats. It is a good choice for a budget protein.

Whey Protein Isolate:This is a purer form of protein because it undergoes longer processing than WPC. The most common filtering form is called ion exchange, where the WPC is taken through an additional filtering step which uses ionically charged clay resins to bind with the protein and separate it from other compounds.

Whey Protein Hydrolysate: This product is when WPC or WPI goes through a further process which breaks longer protein chains into shorter ones. This means the protein is much easier, and therefore faster, to digest.

Whey protein is being extracted from cow's cheese. The element that makes whey protein extremely valuable is its rapid digestion ability. Nowadays, it is widely known that consuming a whey protein shakes immediately after workout is most beneficial for muscle development.

Whey protein as whey isolate or hydrolysate is rapidly absorbed compared to other proteins like casein (milk protein) and as a result it is a good post workout beverage for any form of exercise.
Micellar casein is the same kind of protein that is in cottage cheese, which is why you'll see numerous bodybuilders consume, and favor buying cottage cheese before lights out.

There are a wide variety of protein bars available on the market. Shopping in health food stores and other specialized places will give you an idea of what's available, but even the best-stocked ones will not have everything. General merchandise retailers, like Costco and Wal-Mart, will likely have excellent prices, but the selection will just as likely be pathetic.
