Biological age measures how your body is aging at the cellular level — separate from your calendar age. It can be estimated from biomarkers, epigenetic clocks, or functional tests. The goal: make your biological age lower than your chronological age.

How old is your body, really?
Your chronological age is just a number. Your biological age — the age your cells, tissues, and DNA actually reflect — is what determines your health trajectory. Enter your epigenetic test result or answer 8 quick questions for an estimate.

This result is an approximate educational score based on self-reported lifestyle inputs and population-level aging research. It is not a clinical measurement and has not been validated as an accurate measure of your individual biological age. The only way to know your biological age with clinical precision is through a validated epigenetic test such as TruDiagnostic TruAge, which measures DNA methylation patterns directly. Consult a qualified healthcare provider before making any health decisions based on this estimate.

The only way to know your actual biological age
Lifestyle estimates give you a directional signal. But the only clinically validated method for measuring biological age is epigenetic testing. TruDiagnostic's TruAge test analyzes your DNA methylation patterns — the most peer-reviewed biological age marker in the scientific literature — and delivers a precise, trackable number. No estimate. No range. Your actual epigenetic age, confirmed by lab analysis.
