About Protein Isolate

Protein isolate is processed to remove most of the fat, lactose, and carbohydrates, resulting in a product that is typically 90% or more protein by weight. Whey protein isolate is the most common form, but plant-based isolates (like soy protein isolate and pea protein isolate) are also available. Isolate is a good choice if you want maximum protein with minimal extras, or if you are sensitive to lactose. Because of the additional processing, isolate usually costs more per serving than concentrate — but comparing price per gram of protein reveals that the gap is often smaller than the label price suggests.
