Optimum Nutrition Gold Standard Whey vs Ascent Native Fuel Whey Isolate

Buy Gold Standard if you want a large tub of a proven blend and don't mind sucralose and acesulfame-K. Buy Ascent if you want a pure whey isolate with no artificial sweeteners and more protein per scoop. Gold Standard is the better-known product with a long review record and a wide flavor range; Ascent is the cleaner-label pick with 25g protein, 5.5g BCAAs and 2.7g leucine per scoop. Owners of Gold Standard praise mixability and taste; Ascent's isolate formula suits lactose-sensitive stomachs better.

• Choose the Gold Standard 100% Whey if you want a big, well-reviewed blend tub for daily shakes and you're fine with artificial sweeteners.
• Choose the Ascent Native Fuel Whey Isolate if you want a pure isolate with no artificial sweeteners and a bit more protein per scoop.
