ℹ A whey protein isolate (often whey isolate) is a dietary supplement and food ingredient created by separating components from milk. Whey is a by-product of the cheese-making process. Whey can be processed to yield whey protein in three forms: whey isolate, whey concentrate, or whey hydrolysate.

The difference between the whey protein forms is the composition of the product, particularly the protein content. Whey isolates contain the higher percentage of pure protein and can be pure enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free.

Whey isolates have had their base component (water) removed and are generally considered almost lactose and cholesterol free — they are typically at least 90% protein.  See More
