Authentic ISO is a grass-fed whey protein isolate powder with 25 g of protein per serving and very little lactose, carbohydrate or fat. It is made for fast absorption after training, and the isolate filtration keeps it thin and easy on the stomach compared with concentrate blends. Reviewers rate it highly for mixing and flavor, though some find the sweetness strong and the tub smaller than expected. It sits alongside other lean isolates like Dymatize ISO100 and NOW Sports Whey Isolate on purity and macros, with fewer added extras.
