What earns us money
- Links to retailers and labs where a purchase earns us a commission. Every one is labelled at the link.
- Labelled sponsored placements in the clinic directory, which are always in their own block and never mixed into organic results.
- Pay-per-lead charges when we pass a clinic an enquiry you chose to send.
The rule that makes it survivable
We only carry a commercial link to a product whose intervention page is graded B or better. If the grade drops below B, the links come down. That removes the most profitable part of the supplement market from us — the things with weak evidence and high margins — which is precisely why the rule is worth having.
Commission rates never vary with what we say. We do not accept payment for a review, a grade, a ranking or a placement in a comparison. See how we make money for every revenue line we have.
Where the disclosure appears
At the link, before the click, in plain words. Not in a footer and not on this page alone — a disclosure you have to go looking for is not a disclosure. This page exists to explain the policy, not to substitute for the label.
Royal Decree 1907/1996 prohibits claims that a product prevents, treats or cures disease without authorisation, and prohibits testimonials of professionals or patients as proof of efficacy. No advertising of prescription-only medicines to the public. Affiliate links are labelled as publicidad at the point of the link.
What we do not do
- Sell our own supplements, tests or programmes.
- Run advertorial or paid editorial of any kind.
- Accept free product in exchange for coverage.
- Use affiliate performance as an input to anything editorial, including which pages we write next.
Questions about this notice go to the routes on the contact page, which lists the specific address for privacy, security, editorial and clinic matters rather than a single inbox that everything disappears into.
