How we rank products
Every product receives an Overall Score (0–100) built from seven sub-scores: ingredient quality, bioavailability, dosage, clean label, certifications, user trust and value. For this page we re-weight those sub-scores for the Families use case, then apply ingredient bonuses and hard penalties (artificial fillers, proprietary blends, poor forms) before ranking. The full methodology is fully deterministic and re-runs whenever a product is edited.
