Our take on the Isopure Zero Carb Whey Protein Isolate

Isopure Zero Carb is a 100% whey protein isolate powder with 25 g of protein, no carbs and no sugar per scoop. It adds 20 vitamins and minerals plus electrolytes, which most plain isolates skip. The isolate base filters out lactose and fat, so it suits low-carb, keto and lactose-sensitive diets. Reviewers call the vanilla creamy and easy to mix, though some find it less tasty than the chocolate and note the price has climbed.
