The whey protein isolate powder range is almost 90-95% protein with limited amounts of carbs and fat. It is also lower in calories. Scientifically, whey isolate goes through an extraction process called "cross-flow microfiltration," which allows the protein to be separated from other components such as lactose. This leaves behind the purest form of protein.

Whey isolate is also low in lactose, may make it make it easier to digest and a good option for lactose-intolerant people. Given its purity, it is generally more expensive than whey concentrate, but it is low in calories, fat, and carbohydrates and lactose ..
