Our approach

Longevity, without the hype

The things that decide most of how long and how well you live are well known: not smoking, blood pressure, cholesterol, blood sugar, fitness and strength. They’re cheap to measure and proven to respond to change.

Newer tests like suPAR and NAD⁺ can be interesting. But none has yet been shown to help healthy people live longer, and we’ll always say so.

Strong evidence acting on the result is proven to help
Limited evidence interesting, but not yet shown to change outcomes
