Whey Protein Isolate

Shop whey protein isolate from Applied Nutrition, Dymatize, Optimum Nutrition, Per4m, Naughty Boy, MUTANT and more. Isolate is the purest form of whey — more processed than concentrate, leaving more protein per serving with less fat, carbs and lactose.

Who it's for: Isolate is the better choice if you're watching calories closely, sensitive to lactose, or just want maximum protein for minimum everything else. It's usually a little pricier than concentrate, but that extra processing is what you're paying for.

A few standouts: Applied Nutrition ISO-XP and Per4m Isolate Zero are both low-fat, low-carb options popular for cutting phases. Per4m Whey Hydrate goes a step further — hydrolysed for even faster absorption, with added electrolytes for training days.
