What does Whey Protein Isolate (WPI) mean?

There are several different types of Whey Protein powders used in supplements. Our Whey Protein is a 100% Whey Isolate. Whey Isolate compared to other types of whey proteins has a higher protein content and lower carbohydrate and fat content per serving. In addition to having lower carbohydrate and fat content to other whey proteins, Whey Isolate has lower lactose content.
