Pros and cons

ISO100 Hydrolyzed Whey Protein Isolate

  • 25 g of protein and about 2.7 g of leucine per 120-calorie scoop, all from whey isolate
  • Informed Choice banned-substance mark on the label
  • Only 2 g of carbohydrate and 1 g of sugar in Gourmet Chocolate
  • Dymatize publishes a full amino acid profile for the flavor
  • buyers frequently praise fast, clump-free mixing
  • About $1.55 per serving for the 5 lb tub, pricier than whey blends
  • Contains soy lecithin and is sweetened with sucralose (plus stevia in the current formula)
  • Some buyers still report bloating despite the isolate base
  • Evidence for a real-world benefit from hydrolysis is thin, so part of the premium is marketing

Naked Whey Grass-Fed Whey Protein (Unflavored)

  • Single ingredient: grass-fed whey protein concentrate with no sweeteners or additives
  • 25 g of protein and 5.9 g of naturally occurring BCAAs per 30 g serving
  • Versatile in recipes because it has no flavor or sweetener
  • Large review base: 4.3 stars from nearly 11,000 buyer ratings
  • Bland, milky taste on its own; most people blend it with other ingredients
  • Clumping and foaming are common complaints without a blender
  • The NSF Contents Certified claim could not be confirmed in NSF's public listings
  • Contains some lactose (2 g sugar per serving), unlike an isolate

Our verdicts

ISO100 Hydrolyzed Whey Protein Isolate

ISO100 is one of the most complete whey isolates you can buy: 25 g of protein per scoop with a published amino acid profile, minimal carbs and fat, and banned-substance certification. You pay a premium over whey blends, and the hydrolyzed angle is more marketing than proven performance edge, but for a lean, well-tested isolate that mixes easily it is a safe pick.

Naked Whey Grass-Fed Whey Protein (Unflavored)

Naked Whey is the simplest way to add whey to your diet: one ingredient, 25 g of protein per serving and a fair price for grass-fed sourcing. It tastes plain on its own and its NSF certification could not be confirmed in NSF's public database, so it suits blenders and bakers better than athletes who need verified testing.
