Pros and cons

Whey+ Grass-Fed Whey Protein Isolate

  • Whey isolate certified under the Truly Grass Fed program
  • NSF contents-certified (Dutch Chocolate and French Vanilla) and Labdoor-certified, with certificates of analysis linked online
  • No artificial sweeteners or dyes, and no added sugar
  • buyers often mention smooth mixing and easy digestion
  • 21 to 23 g of protein per scoop, a little below leading isolates
  • About $2.06 per serving, with a higher list price on the brand site
  • Stevia is noticeable to some reviewers
  • Not in the NSF Certified for Sport or Informed Choice programs, and the Amazon listing states it contains milk and soy

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

Whey+ Grass-Fed Whey Protein Isolate

Legion Whey+ is one of the most credible naturally sweetened whey isolates, pairing certified grass-fed sourcing with public lab testing. You get slightly less protein per scoop than some rivals and pay a premium, but for buyers avoiding artificial sweeteners who want proof of what is in the bag, it is an easy recommendation.

Full review

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.
