How we score
Each product earns an Effectiveness Match score (0–100) measuring how closely its active ingredient doses match the evidence-based clinical reference for its category. Proprietary blends and amino-spiked formulas are penalised because they hide the real dose. We are independent — scores are never influenced by brands or affiliate deals.
Informational only — not medical advice. Buy links are affiliate links; we may earn a commission at no extra cost to you. This never affects scoring.
