ISO100 is a hydrolyzed whey protein isolate powder with 25 g of protein and 5.5 g of BCAAs per scoop, made through cross-flow microfiltration and enzymatic hydrolysis. It is filtered to remove most lactose, fat and carbs, which makes it a fast-digesting option for post-workout use and easier on the stomach than many concentrates. Reviewers consistently rate the taste and mixability highly, and it is one of the most widely used isolates worldwide. Against cheaper whey concentrates it costs more per gram of protein but delivers a leaner macro profile and thinner texture.
