Thorne vs Pure Encapsulations vs NOW Foods vs Nature Made: How the Top Supplement Brands Actually Score
Every "best supplement brands" article cites the same four names — Thorne, Pure Encapsulations, NOW Foods, Nature Made — and points at NSF and USP third-party certifications. Certifications are a floor, not a ranking. This is what those four brands actually score across our full product-integrity rubric: evidence quality, dose disclosure, manufacturing standards, safety, transparency, sustainability. Same rubric, same weighting, applied to every product from all four vendors we carry. Read the rubric →

How the scoring works
Every product is scored on six dimensions — evidence (RCT quality supporting the active ingredients at the label dose), formulation (dose adequacy, bioavailability form, redundancy), manufacturing (third-party testing, GMP, facility audits), safety (adverse-event profile, interactions, dose ceiling), transparency (dose disclosure vs proprietary blends, honest marketing), and sustainability (sourcing, packaging, corporate practice). Tier thresholds: Elite 85+, Verified 70–84, Standard 50–69, Rejected 0–49. Rejected products stay listed with reasons. Full rubric →
