Questions, answeredAnswers to what shoppers ask us most. These same answers power the FAQ schema on this page.
Whey protein isolate (WPI) is a whey protein that has undergone additional filtration compared to whey concentrate, resulting in a higher protein percentage and lower levels of fat, carbohydrate and lactose. It's a popular choice for those wanting a leaner, more concentrated protein source.
WPI contains less lactose than WPC due to its additional filtration, which makes it easier to tolerate for many people with mild lactose sensitivity. It isn't completely lactose-free though, so anyone with a significant intolerance may prefer a dairy-free option like beef protein isolate or plant-based protein.
WPI typically costs more than WPC because it requires additional filtration to remove more of the fat, carbohydrate and lactose, leaving a higher percentage of protein. This extra processing step adds to production costs, which is reflected in the price.
