About

We check what the longevity industry claims.

Caveat is the claim-checker the longevity industry didn’t ask for, and that readers can finally trust.

Who’s behind it

Niko Hems

MSc Longevity · MSc Business & Data Analytics

An evidence-literate insider: a master’s in longevity, a second in business & data analytics, and day-to-day work inside a longevity clinic. Not a famous aging scientist, the consumer’s independent guide to the longevity marketplace, with the method and the receipts to back every verdict.

How we stay independent

No industry money. Full stop.

We take no money from any company whose products, devices, tests or supplements we cover, no sponsorships, no pay-for-verdict, no affiliate revenue on anything we rate.

Disclosure: Niko works clinically in longevity care. Caveat is independent of that employer, we do not check or endorse the clinic’s own products, and the clinic neither funds nor controls Caveat.

Absence of evidence isn’t evidence of absence, and we’ll always say so.
