Best Clean Protein Powders for 2026

January 5, 20266 min read

Finding a protein powder that's actually clean is harder than it should be. Most are loaded with artificial sweeteners, seed oils, gums, and fillers. Some even contain concerning levels of heavy metals. We tested and evaluated over 10 popular options.

What We Looked For

  • Third-party testing for heavy metals (lead, cadmium, arsenic)
  • No artificial sweeteners (sucralose, acesulfame K, aspartame)
  • No seed oils or inflammatory additives
  • Clean protein sources (grass-fed whey isolate, beef protein)
  • Transparent labeling (no proprietary blends)

Our Top Picks

LEGION Whey+ Protein — Grass-fed whey isolate, 22g protein, naturally sweetened with stevia. Informed Sport certified.

Equip Foods Prime Protein — Single-ingredient beef protein isolate. 21g protein with literally one ingredient. Paleo and Whole30 approved.

Both are available in our Supplements recommendations.
