    There are no added sugars in Purist® grass-fed whey protein isolate.​

    Whey protein isolate is a highly refined form of whey protein that contains at least 90% protein by weight. The term "isolate" refers to the additional processing that removes most of the fat, lactose, and carbs, making it a purer and more digestible protein source. This makes it ideal for athletes, lifters, and anyone looking for a lean protein with minimal extras. Compared with whey concentrate, isolate has higher protein content (90%+ vs. 70-80%), lower lactose, and less fat and carbs, making it easier to digest and a great choice for muscle recovery. It also absorbs faster, making it especially effective for post-workout nutrition. If you want a clean, high-protein option without excess fillers, whey isolate is one of the best choices.
