- bodybuilders, especially competition phase

Whey protein isolate (WPI) has the highest protein count among all protein sources. It is virtually fat, carb, and lactose free. Thus, they are the ideal protein supplement for sports enthusiasts who are lactose intolerant. WPI is a fast absorbing protein.
WPI is most commonly derived via either the cold flow micro-filtration process or ion-exchange process. The best being cold-flow micro-filtration which keeps the bioavailability of the protein intact. Ion-exchange filtration treatment achieves a slightly higher protein count, but compromises the valuable bio-available microfactions that are beneficial to intestinal health.
