Bulletproof
No certification; 2020 FDA cGMP warning letter · Mid-range
States it works with 'accredited third-party labs' but names no third-party certification programme for its finished supplements, and appears in neither USP's Verified listing nor NSF's dietary-supplement database. FDA issued a warning letter on 20 March 2020 after a 2019 inspection, citing current Good Manufacturing Practice violations under 21 CFR Part 111 and deeming its Chocolate and Vanilla Collagen Protein adulterated. Its named certifications (Rainforest Alliance, Specialty Coffee Association) apply to coffee sourcing, not supplement quality.

Bulletprooftesting & certifications — FAQ
Is Bulletproof third-party tested?
Bulletproof reports the following quality programmes: No third-party certification program confirmed. Third-party testing checks a product's identity, potency, and purity against its label. We reproduce what the brand publishes; where the certifier keeps a public registry (NSF, USP, Informed Sport), look the specific product up there before relying on it — a company-wide claim is not a batch certificate.
How we assess supplement brands
Supplements aren't FDA recall-rated like prescription drugs, so we don't assign a recall-safety score here. Instead we report what a brand is independently verified for — NSF, NSF Certified for Sport, USP Verified, Informed Sport, cGMP, and batch testing — the signals that actually separate supplement quality. This is general reference, not medical advice; always consult a professional.
