About Our Team
We are a team of licensed healthcare professionals committed to providing evidence-based supplement guidance you can trust.
Cutting through the noise in supplement marketing
Women 25-50 with hair thinning, brittle nails, or nail fungus face conflicting advice across Reddit, TikTok, and generic blogs — opinions, not evidence.
NailHairVitamins combines personalized matching, interactive diagnostic tools, clinical evidence, and honest reviews — all authored by licensed professionals.
We earn through affiliate commissions, fully disclosed. Commission rates never influence rankings.
What we believe in
Evidence Over Hype
Every recommendation links to peer-reviewed studies from PubMed and NIH. We cite our sources — always.
Radical Transparency
Commission rates never influence rankings. We disclose every affiliate relationship. Period.
Personalized Matching
Age, medications, pregnancy, acne sensitivity — our tools account for your unique biology.
YMYL Responsibility
We never claim supplements cure or treat conditions. "Supports" language. Always consult your doctor.
