Affiliate Disclosure and Purchase Links

Understand affiliate purchase links on Officials Supplements, retailer-controlled buying terms, and the limits of catalog product information.

Some purchase links are affiliate links

We may receive a commission when a reader makes a qualifying purchase through an affiliate link. A commercial link does not mean that we have personally tested the product or that its advertised health claims are established.

Check the retailer’s current terms

The linked retailer controls the price, delivery, recurring charges, refunds, and availability. Read the checkout and terms before making a purchase. Catalog copy is not a promise that an old price, promotion, or return policy is still available.

Compare before buying

Ask for a current readable label, check ingredient amounts and warnings, and consider relevant independent evidence. Purchase buttons should not be treated as medical advice or a guarantee of suitability.
