How we are funded
Affiliate disclosure
Last updated: July 2026
The Supplement Compass is a reader-funded publication. This page explains, in plain language, how we earn money and how that does and does not affect what you read here.
The short version
Some links on this website are affiliate links. If you click one and buy a product from the manufacturer's official website, we may receive a commission. You pay exactly the same price whether you use our link or not. That commission is what keeps this site running and lets us publish independent reviews without charging readers.
Our independence
We are not the maker of NeuroZen and we are not paid by the manufacturer to write a positive review. Manufacturers do not see our reviews before they publish, do not approve our scores, and cannot pay to change them. We publish criticism, low scores, and the complaints of unhappy buyers when the evidence supports them, and our commission is identical whether a review is glowing or lukewarm. If a product is not worth buying, saying so protects the reader trust our business depends on.
FTC compliance
We follow the U.S. Federal Trade Commission's Guides Concerning the Use of Endorsements and Testimonials in Advertising (16 CFR Part 255). That is why you see a clear disclosure near the top of every page that carries affiliate links, next to the buttons themselves, and here in full. We want the commercial relationship to be obvious, not buried.
How we choose what to link
We only ever link to a product's official manufacturer website. We do not send readers to third-party marketplace listings, because those can be counterfeit, expired, or ineligible for the manufacturer's guarantee. The affiliate links on our pages pass through a redirect and carry tracking parameters so we can see which pages send purchases; that data tells us nothing about you personally.
How our reviews are written
Our scoring method, our reviewer, and the source of our user data are described in detail on the how we review page. In short: a repeatable eight-criteria score, professional judgment, and an honest account of user feedback, including the negative kind.
