Isopure Zero Carb Whey Protein Isolate
At a glance
Summary
Isopure Zero Carb Whey Protein Isolate scores 44/100. The protein source is strong — 100% whey protein isolate delivering 25g protein with zero carbs and zero sugar at just 110 calories. A comprehensive vitamin and mineral blend with 20+ micronutrients adds genuine nutritional value. However, the product is artificially flavored with zero ingredient transparency, contains soy lecithin (typically GMO/hexane-derived), sucralose (a chlorinated artificial sweetener), xanthan gum, and silicon dioxide. Cheap synthetic vitamin forms like cyanocobalamin and sodium selenite further undermine the quality.
