Every brand meets our elevated quality standards. But we don’t stop there. As an added layer of assurance, select products from popular or problematic categories are subjected to enhanced testing by independent third-party labs to confirm potency and purity claims, giving you more trust in the products you recommend. Brands cannot pay for inclusion in Enhanced Testing or to receive an “Enhanced Testing” badge, ensuring that decisions remain clinically-focused and unbiased.
