  • No artificial sweeteners or dyes, and no added sugar
  • buyers often mention smooth mixing and easy digestion

Our verdicts

Whey Protein

GHOST Whey earns its popularity on flavor: few powders taste this much like the dessert or cereal on the label. The formula underneath is a solid, fully disclosed whey blend, but with no third-party certification and a price above $2 per serving, it is a treat-yourself pick rather than the best value or the safest choice for tested athletes.

Full review

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.
