Find your biological age in 2 minutes. No blood test. No wearable. Just answers.
Enter what you know — basic biometrics, lifestyle, optional bloodwork. We estimate a biological age and break down what's adding or subtracting years. Educational only; not medical advice.
PhenoAge (Levine et al., Aging, 2018) is a published biological-age estimator built from 9 standard blood markers plus chronological age, validated against mortality outcomes in NHANES. Enter your most recent values for a publication-grade estimate.
Trained on the hallmarks of aging and thousands of studies. Ask anything — it builds you a personalized plan.
Educational only — not medical advice. Conversations are AI-generated.
Every point in your score traces back to real biology — the hallmarks that drive aging, the biomarkers we read, the interventions with evidence, and the research we track daily.
How efficiently your cells still make power — and why it fades. The biggest lever most people ignore.
"Zombie" cells that stop dividing but won't die — leaking inflammation into the healthy tissue around them.
The slow-burn immune activation — "inflammaging" — that quietly speeds up nearly every age-related disease.
The clearest blood signal of "inflammaging" — one of the strongest movers of your score.
Where your metabolism sits today — creeping glucose adds years quietly.
The single best predictor of all-cause mortality — cardiorespiratory reserve.
Quiet whole-body markers from a routine panel that PhenoAge weighs heavily.
Ten organ-specific clocks validated across China & US cohorts; brain aging was the strongest single predictor of mortality.
A 24-year longitudinal cohort shows the pace of aging — not just its starting point — forecasts when disease and death arrive.
A state-of-the-art review of how proteomic and epigenetic clocks are moving from research into real clinical decision-making.
Early data suggest senolytic compounds can lower epigenetic-age markers and cut systemic inflammation in older adults.
