Chronological age is fixed the number of years since you were born. Biological age is dynamic how old your body actually is, measured by how your DNA is being expressed. Two people with the same birthday can have biological ages a decade apart.
Our test runs three of the most validated epigenetic clocks GrimAge, PhenoAge, and Horvath across 9 million DNA methylation sites. The result is a single number that predicts mortality risk, healthspan, and the rate at which you are ageing right now.
