Nutrafol
NSF Certified for Sport hair supplement · Premium
Hair-growth line whose nutraceuticals hold NSF Certified for Sport — verified in NSF's own database and announced by NSF directly, which is stronger than the 'NSF Contents Certified' the company itself advertises. Certification covers the hair-growth products (Women, Men, Men 50+, Postpartum, Women's Vegan, Women's Balance) and Clear Skin, not everything it sells. Its efficacy evidence comes from company-sponsored randomised, double-blind, placebo-controlled trials of roughly 40 to 80 participants each over six months — placebo-controlled, but sponsored and small.

Nutrafoltesting & certifications — FAQ
Is Nutrafol third-party tested?
Nutrafol reports the following quality programmes: NSF Certified for Sport (hair-growth products and Clear Skin), NSF Contents Certified (company-stated). NSF certification is an independent, third-party program that verifies a product actually matches 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.
Is Nutrafol NSF Certified for Sport?
Nutrafol states that products carry NSF Certified for Sport. NSF Certified for Sport screens each batch against 280+ substances banned in sport and confirms the label is accurate.
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.
