Whey protein isolate (WPI) is a type of whey protein that has been processed to remove most of the lactose and fat. This makes it a good choice for people who are lactose intolerant or who are trying to lose weight. WPI is also a highly concentrated source of protein, with a protein content of 90% or more.

Whey protein isolate (WPI) is often used by athletes and bodybuilders to build muscle mass. It is also used by people who are trying to lose weight, as it can help to reduce hunger and cravings. WPI can also be used to improve overall health and fitness.
