Pros and cons

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

100% Grass-Fed Whey Protein Isolate

  • 28 g of protein per scoop from grass-fed whey isolate
  • Listed in NSF's Certified for Sport database and certified by Informed Choice (per the brand)
  • Every ingredient disclosed by weight, with batch test results published online
  • No artificial sweeteners, dyes or preservatives
  • buyers frequently describe it as easy on the stomach
  • About $2.17 per serving for the 30-serving tub, well above whey blends
  • Stevia can leave an aftertaste some people dislike
  • Made on equipment that also processes eggs, soy, wheat, shellfish, fish oil, tree nuts and peanut oil, and some flavors contain peanuts
  • Mostly sold through the brand site and Amazon, so in-store discounts are rare

Our verdicts

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.

Full review

100% Grass-Fed Whey Protein Isolate

For shoppers who prioritize ingredient transparency and third-party verification, this is one of the strongest whey isolates available: 28 g of protein, a short stevia-sweetened ingredient list, NSF Certified for Sport status and public batch testing. The trade-off is price, at more than $2 per serving, and stevia's flavor will not suit everyone.
