Types of Whey Protein?
There are three main types of whey protein: Whey Protein Concentrate Low in fat 75% pure protein by weight Lower cost Whey Protein Isolate Purest form of whey protein Contains 90% or greater protein with minimal lactose (<1%) and virtually no fat Higher cost Hydrolyzed Whey Protein Hydrolysis is the process which breaks down the protein chains into small fractions called "peptides". Easily digested and less potential for allergic reactions. There are also many blends of the three types discussed above available. Typically the cheapest form of whey will make up the highest content with the remaining content being based on cost. So a blend would be largely concentrate, with only small amounts of isolate. This is why you can find 5 lb tubs pretty cheap, especially when compared to a smaller container of pure isolate.
