DNA methylation-based epigenetic clocks serve as accurate biomarkers for predicting biological age, disease risk, and mortality, often outperforming traditional chronological age metrics.

Use epigenetic age as a diagnostic tool to assess your biological aging rate relative to your chronological age. While you cannot change your birth date, tracking these biomarkers (via blood tests) can help identify early risks for diseases like diabetes, cardiovascular issues, or cognitive decline, allowing for earlier lifestyle or medical interventions.
