Biological Age
Measure biological age — then bend it downward
The goal is to measure how old a body actually is, biologically, and then slow, halt, or reverse that pace — so years lived count for less than years of health gained. Chronological age only counts birthdays; biological age reflects how the body has actually worn and repaired itself, and that is the number we want to move.
Two people born the same year can be a decade apart in how their cells, blood vessels, and immune systems have aged. Biological age — estimated from epigenetic, blood, and functional markers — predicts disease and disability better than the calendar. If a person can see their true biological age and watch it respond to prevention and treatment, aging stops being an invisible fate and becomes something measurable, trackable, and — eventually — modifiable.
We are building the capability to quantify biological age reliably and act on it — standardized aging clocks a clinician can order, paired with interventions that measurably lower the score. The honest near-term goal is accurate measurement and slowing the pace of aging; reversing biological age in humans is a frontier still being established in the laboratory.
How it works
Measure the pace of aging Demonstrated
Epigenetic clocks (DNA-methylation), proteomic and inflammatory markers, and functional tests estimate biological age and the rate it is changing.
Reduce known accelerators Clinical
Treating the drivers that speed aging — chronic inflammation, metabolic disease, poor sleep, smoking — is established clinical care today.
Slow the underlying biology Demonstrated
Interventions targeting senescent cells, metabolism, and cellular stress slow aging markers in research and early trials.
Reverse biological age Frontier
Returning aged tissue to a younger state is shown in laboratory and animal models — frontier, not yet a human therapy.
Cited as evidence the capability is real — not as partners or endorsers.
Government & programs
National Institute on Aging (NIA, NIH) · NIH geroscience and Interventions Testing Program. These public programs fund the foundational research that shows biological aging can be measured and influenced.
Universities & institutes
Buck Institute for Research on Aging · Harvard and Stanford aging-biology centers · academic epigenetic-clock laboratories. Academic labs developed and validated the aging clocks now used in research.
Enabling science base
epigenetics · proteomics · senescence biology · biostatistics of aging clocks. — the established disciplines this capability is built upon.
The technologies: DNA-methylation aging clocks, proteomic and inflammatory aging panels, functional biomarkers of aging (grip strength, gait, organ-specific scores), and longitudinal tracking that measures whether an intervention is actually working.
Validated aging clocks Demonstrated
Multiple DNA-methylation clocks predict mortality and disease risk in large research cohorts.
Organ-specific aging Demonstrated
Blood-based measures can now estimate how fast individual organs are aging, in research settings.
Pace-of-aging measures Demonstrated
Tools that track the rate of aging over time make it possible to test whether an intervention slows it.
Reversal in models Frontier
Partial cellular reprogramming reverses aging markers in animals — frontier, not human-ready.
The honest challenges: aging clocks are powerful research tools but are not yet standardized clinical diagnostics, and a lower score does not yet guarantee a longer healthy life — that link is still being proven. Reversing biological age in people remains frontier. The capability is real and advancing; we present each piece exactly at the stage it has reached.
The future, fully built
A person can see their true biological age, understand what is driving it, and watch it improve as prevention and treatment take hold — turning aging from an invisible fate into a measured, manageable part of lifelong health.
The proof, for this capability
Cited as evidence the capability is real, not as partners or endorsers.
Clinical anchor
Treating the accelerators of aging — inflammation, metabolic disease, poor sleep — is established care. Stage: Clinical.
Demonstrated measurement
Epigenetic and proteomic aging clocks predict health outcomes in large cohorts. Stage: Demonstrated.
Frontier reversal
Reversing biological age in tissue is shown in the lab and in animals. Stage: Frontier.
Honest framing
Real organizations are cited as evidence the capability is real — not as partners or endorsers. Measurement is far ahead of reversal; nothing here is presented as a finished anti-aging cure.
Help build this future
Every signature grows the movement to make measuring and improving biological age real — and free at the point of need.
