Which Protein Powders Are Clean Label Project Certified?
Which Protein Powders Are Clean Label Project Certified?
None of the protein powders in Label Lookout's own picks carry the Clean Label Project's Purity Award today. That is not the same as saying they are untested. Here is what the badge actually checks, why it is hard to find on a protein powder shelf right now, and which of our picks carry comparable independent testing instead.
What the Clean Label Project Purity Award actually tests
The Clean Label Project is a nonprofit testing group. Its Purity Award is a specific certification a product earns after the organization's lab screens a batch for heavy metals, pesticides, and other industrial contaminants, then publishes the result. That is different from a brand simply printing "third-party tested" on the label with no named lab, no public data, and no logo behind it.
The group's own research is why this category needs the scrutiny. The Clean Label Project tested 134 popular protein powders and found that 70% contained measurable lead, with some exceeding California's Prop 65 safe harbor limit. Our guide to protein powders without lead or heavy metals covers those numbers and what drives them in more depth.
A searchable public database is part of what makes the Purity Award useful. You can look up a specific product and see whether it passed, rather than taking a marketing claim at face value.
Why our current picks don't carry it, and what they carry instead
Certification programs cost money and require a brand to submit for testing, so plenty of genuinely clean products simply have not gone through this specific one. That is the case with the protein powders we recommend today. Here is what they carry instead:
- LEGION Whey+ Protein holds Informed Sport certification, a UK-based program that tests every batch for banned substances and contaminants, heavy metals included, and Legion posts the Certificate of Analysis per batch.
- NAKED's whey and pea powders both carry NSF marks, NSF Certified and NSF Contents Certified respectively, which verify the label matches the contents and screen for heavy metals and pesticides.
Those are not the Clean Label Project's badge specifically, but they check for the same category of risk, using outside labs instead of brand self-reporting.
One real example of a Clean Label Project Purity Award product does exist on the market. WICKED Protein's Clear Whey Isolate carries the badge on its Amazon listing. We have not vetted or added it to our own catalog yet, so we are naming it here as a factual answer to the question, not as a recommendation.
What this means if you're shopping by certification
If the Clean Label Project badge specifically is what you searched for, the honest answer is that it is rare on protein powder shelves right now, our own picks included. If what you actually want is proof that a product was tested by someone other than the brand that sells it, Informed Sport and NSF Certified do the same job, and both show up on the picks below.
The picks that carry comparable independent testing
- LEGION Whey+ Protein: best overall. Grass-fed Irish whey isolate, Informed Sport certified, with a published Certificate of Analysis per batch.
- NAKED 100% Grass-Fed Whey Protein Powder: best NSF Certified whey. One ingredient, and NSF Certified means an outside lab checked the label against the contents and screened for contaminants.
- NAKED Pea Protein Powder: best plant-based. NSF Contents Certified, useful if you are avoiding dairy and still want independent verification.
- Equip Foods Prime Protein: best single-ingredient. Just grass-fed beef protein isolate, with nowhere for anything else to hide.
- PRIMA ANCESTRAL Grass Fed Protein Bars: best for on-the-go. Grass-fed beef protein in bar form for days a shake isn't practical.
- LEGION Micronized Creatine Monohydrate: best if you are stacking creatine alongside protein. Same Informed Sport testing standard as Legion's Whey+.

Bottom line
No protein powder in our current picks carries the Clean Label Project's Purity Award, but that badge is only one valid way to prove independent testing. Informed Sport and NSF Certified check for the same category of contaminant, using outside labs instead of brand self-reporting, and several of our picks carry one of them.
