Clean Label Project explained

The contaminant cert no one talks about

The Clean Label Project (CLP) is a nonprofit that tests consumer products — baby food, protein powders, supplements, electrolyte mixes — for the contaminants the FDA does not require brands to disclose: heavy metals, pesticides, plasticizers, mycotoxins, BPA, antibiotic residue, and more.

What CLP tests for

Why this matters

The FDA does not require brands to test for or disclose any of the contaminants above. A protein powder that passes FDA review can still contain heavy-metal levels well above what California Prop 65 considers safe. CLP testing closes that gap.

What "Clean Label Project Certified" means

CLP awards a certification to brands whose products pass their full testing panel. The bottle gets a seal. The cert is published on the CLP website with the test date and detailed results.

Unlike NSF Certified for Sport (which is athlete-focused) or USP Verified (which is potency-focused), CLP is the certification that targets contamination specifically. If you care about what is NOT in the product as much as what IS, CLP is the cert to look for.

Brands that carry it

122 brands are currently CLP-certified across baby food, supplements, protein, and electrolytes. The cert is especially common on:

Frequently asked

Is Clean Label Project the same as USDA Organic?
No. USDA Organic certifies the growing process. CLP tests the finished product for contaminants regardless of farming method. They are complementary, not redundant.
Does CLP test every batch?
CLP tests product samples representative of production. Brands re-certify periodically, and the cert is tied to the product, not a specific batch number.
Why does CLP focus on baby food so heavily?
CLP launched out of independent testing that found heavy metals in 95% of baby food brands. Baby food remains a core focus because the contamination risk is highest there.
Can I trust a brand with no CLP cert?
You can — but you have less verification. Many brands publish their own internal testing, and some get NSF or USP certs instead. ScanCheck cross-references all of those when you scan.
