Support the project

Smart Longevity is an independent project on evidence-based longevity. We sell no supplements and no places in the catalog. The portal runs on subscriptions and reader contributions — which is why our calculators show what the research says, not what an advertiser would prefer.

Why this costs money

Medical review

A physician reviews every calculator and every article: formulas, units, reference ranges, contraindications. That is hours of specialist work — and the main reason our numbers can be trusted.

Professional translation

The English version of the portal is not machine translation. Terms, scales and legal wording are translated by a human who understands the subject.

Live events and expeditions

Conferences, clinics and longevity labs: we travel, film, ask questions and bring back a first-hand analysis — instead of retelling somebody’s press release.

What already works — free, and without advertising

48calculators with their formulas in the open
289lab markers explained in plain language
0third-party trackers on the site
0calculations stored — your input is never kept

All of it is open without an account and without payment. The missions are about what comes next.

Transparency

Smart Longevity is a commercial project. A contribution is voluntary support, not a charitable donation: it is not tax-deductible and grants no tax benefit. A contribution does not create any agreement for the provision of medical services and is not payment for medical care. The materials on this portal are educational and do not replace consultation with a physician.
