Our evaluation approach
We compare products against relevant criteria such as ingredient identity and dosage, available evidence, label transparency, manufacturing documentation, pricing, return terms and relevant warnings. Product-specific conclusions are only published after review.
Evidence and testing
We distinguish manufacturer statements from independently verified information. We do not claim firsthand product testing, medical review, clinical validation, customer surveys or numerical ratings unless they actually occurred and can be documented.
Commercial relationships
We may receive affiliate commissions from qualifying purchases. Financial relationships are disclosed and should not determine factual scores or rankings. Sponsored placements, if any, are clearly labeled.
Corrections and updates
Product labels, prices, promotions and availability change. We aim to revisit published comparisons and correct substantiated errors. Readers can contact us through the contact page.
