Last updated: 19 August 2026. If you are reading about supplements, tests or devices, you are entitled to know who paid for the article. On this site, nobody did.
What we do not do
- No display advertising. There are no ad slots, ad networks or sponsored banners on this site.
- No sponsored content. We do not accept payment, product or hospitality in exchange for coverage, for a review, for a mention or for a link.
- No guest posts and no paid links. Every link on this site was placed by our editorial team because it helps the reader, and no link on this site has ever been sold.
- We sell nothing. We do not sell supplements, tests, devices, courses, consultations or subscriptions.
The connection we do have
Longevity Lab links frequently to Smart Longevity (smartlongevity.us), a companion site of health calculators, screening tests and a medical glossary. That site is operated by the same people who publish Longevity Lab. Under the United States Federal Trade Commission’s endorsement guides, that is a material connection, and we disclose it plainly rather than letting the links read as a neutral third-party recommendation.
What that connection is worth stating precisely: Smart Longevity is free to use, it sells nothing, it carries no advertising and it takes no payment from anyone whose product it mentions. We link to it because its calculators compute the scores our articles explain. But you should weigh those links knowing whose site they lead to, exactly as you would weigh any other self-reference.
Affiliate links
We currently use no affiliate links anywhere on this site. No link here earns us a commission, a referral fee or a share of a sale. If that ever changes, we will mark the affected links clearly, disclose the relationship at the top of the article that contains them, and update this page before any such link goes live — as the FTC’s guides, the UK Advertising Standards Authority’s CAP Code and equivalent EU consumer law all require.
How products get mentioned
A supplement, a test or a device appears in an article for one reason: there is published research about it that a reader would want to understand. We report what the evidence shows, including when it shows that something does not work, and we say plainly where the data is thin. Manufacturers get no say in what we write, no preview of it and no right of reply beyond correcting a factual error, which anyone can ask us to do.
How the site is funded
Longevity Lab is self-funded by its publisher. It has no advertisers, no sponsors and no commercial backers with an interest in what it concludes. If that ever changes — if we take sponsorship, run advertising or accept grant funding — we will name the funder on this page.
Reporting a breach of this policy
If you find something on this site that looks like undisclosed advertising, tell us at info@longevity-lab.fit and we will investigate and correct it.
