How we handle claims
Seller statements are described as seller-reported rather than adopted as independent conclusions. Ingredient studies are not presented as finished-product trials. We avoid disease-treatment claims unless discussing them critically or explaining why evidence does not support transfer to the product.
Updates and conflicts
Commercial terms can change. Core buyer pages carry update dates, and readers are directed to verify the live checkout before purchase. When seller statements conflict — such as differing guarantee or dosage wording — we disclose the conflict rather than silently choose the more favorable claim.
Affiliate influence
Affiliate compensation may support this site, but it does not justify invented ratings, hidden disclosures, fabricated testimonials or unsupported conclusions. Commercial links are marked with rel="nofollow sponsored noopener".
