Hey PH! I'm Maciej, a solo developer from Poland. I built SupplementChecker because I got tired of Googling "is [brand] safe" and getting nothing but affiliate blogs and paid reviews. There's no single place to check if a supplement brand has FDA recalls, third-party testing, or real certifications. So I built one. SupplementChecker pulls data from: - FDA recall database (573+ recalls tracked) - NSF International certifications (1,020 brands) - USP Verified products - Informed Sport/Choice databases - NIH Dietary Supplement Label Database Every brand gets a transparent trust score — you can see exactly how it's calculated. No pay-to-play, no sponsored rankings. 4,143 brands indexed so far. The whole thing is free. I make a small commission if you buy through affiliate links, but the scores are never influenced by that. Built with: Astro (SSG), Python ETL pipeline, Supabase, Cloudflare Pages. Total hosting cost: ~$0/mo. Would love your feedback — what brands should I add? What data sources am I missing?
