We believe you have a right to know exactly how this site works and how it earns revenue. This page explains it fully.
This website earns money by recommending products. When you click a link on this site and make a purchase, we may receive a commission from the seller — at no extra cost to you. This is called affiliate marketing, and it's how this site funds itself.
The commission we receive does not change the price you pay. It does not influence what we write. Positive reviews are not for sale, and we disclose critical findings regardless of whether they help or hurt our earnings.
Links marked with "nofollow" or leading to external retailers may be affiliate links. If you purchase through them, we earn a commission. The price you pay is identical whether you use our link or go directly to the seller's website.
Our editorial content is written before, not after, commercial decisions. A product gets recommended because the evidence supports it — not because the commission rate is high. Products we find lacking receive critical reviews even when that costs us revenue.
We are required by the US Federal Trade Commission (FTC) to disclose this relationship. This page, and the brief disclosures on individual review pages, satisfy that requirement.
The following points explain in detail how commercial relationships operate across this website. If you have questions not answered here, see the contact section at the bottom of this page.
Some links on this site are affiliate links — unique URLs that allow the retailer or manufacturer to track that a visitor came from this site. When a qualifying purchase is made through one of these links, we receive a commission. These links are typically the "Check Price," "Buy Now," or "Visit Official Website" style buttons and calls-to-action found throughout our reviews.
Commission rates vary by product and programme. We participate in affiliate programmes operated directly by manufacturers and, in some cases, through affiliate networks. Commission rates are set by the programme operator — we do not negotiate higher rates in exchange for more favourable editorial treatment.
Commissions do not buy positive reviews, editorial placement, higher ratings, suppression of critical findings, or any other form of editorial influence. A product that earns us a high commission rate gets the same honest evaluation as one that earns nothing. If the evidence doesn't support the claims, we say so — regardless of the commercial relationship.
All reviews are researched and written by Michael Stevens based on publicly available ingredient science, manufacturer label disclosures, clinical literature, and user-reported experience. No manufacturer has reviewed, approved, or had input into any editorial content published on this site prior to publication.
The commission we earn is paid by the manufacturer or retailer — not by you. The price you pay when purchasing through an affiliate link is identical to what you would pay going directly to the seller's website. In some cases, affiliate arrangements include exclusive discount codes, which would result in you paying less, not more.
Affiliate links may appear anywhere on this site — in review body text, in call-to-action buttons, in comparison tables, in pricing sections, and in the navigation bar. You do not need to use these links to access the products reviewed. You are always free to navigate directly to the manufacturer's or retailer's website.
This disclosure is provided in compliance with the United States Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255) and equivalent regulations in Canada (ASC Guidelines) and the United Kingdom (CAP Code).
The FTC requires that any material connection between a reviewer and a product — including receiving compensation — be clearly disclosed to readers. This page constitutes that disclosure for all content published on this site.
If you have concerns about whether a specific piece of content is in compliance with applicable disclosure requirements, please contact us using the details below.
No. Review scores and recommendations are determined by ingredient evidence, formulation transparency, dosage accuracy, guarantee terms, and value for money — not by commission rates. Products with higher commission rates have received critical or negative reviews on this site when the evidence warranted it.
Occasionally, manufacturers offer complimentary products for review purposes. When this occurs, it is disclosed within the relevant review. Receiving a product at no cost does not guarantee a positive review. Our findings are based on the ingredient evidence and label analysis, not on the experience of receiving the product.
No. Manufacturers cannot pay for inclusion, placement, or any form of featured treatment. Reviews are selected based on consumer search interest, product relevance, and the editor's assessment of whether a review would provide value to readers. Manufacturers are not informed in advance that they are being reviewed.
Any link that leads to a manufacturer's or retailer's sales page should be assumed to be an affiliate link. Informational links to sources such as PubMed, the NIH, the Mayo Clinic, or Wikipedia are not affiliate links. If you are ever unsure, you can hover over a link to inspect the URL before clicking.
If you return a product and receive a refund, the affiliate commission associated with that purchase is typically reversed. Your return and refund rights are governed entirely by the manufacturer's or retailer's return policy — they are unaffected by the affiliate relationship. We always recommend purchasing through the official website to ensure full guarantee eligibility.
No. This site is an independent review resource. It is not owned, operated, or funded by any supplement manufacturer. The affiliate relationship is commercial only — it does not extend to editorial control, content approval, or any form of business relationship beyond the commission arrangement.
