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)
