Criterion Health earns referral commissions when readers purchase through certain outbound links. This page explains how that works and why it does not determine our rankings.

We comply with Federal Trade Commission guidelines on endorsements and affiliate marketing. When you click an outbound link and buy a product, we may receive a referral commission from the retailer or brand at no added cost to you.

Commissions are paid by the merchant. Our compensation does not change the price you pay, and we disclose these relationships on the pages where they apply.

Rankings, ratings, and evaluations are decided by our editorial standards, not by commission rates. A product does not rank higher because it pays us more, and we do not accept payment for favorable coverage.

Product facts are checked against supplied labels and published sources wherever possible. Educational content is general information, not medical advice.

Review our product evaluations and comparison tables, with each relationship disclosed where it applies.
