Epigenetic clocks (DNAmAge) are currently the most robust biological age predictors, strongly correlating with chronological age and independently predicting all-cause mortality, cancer mortality, and various aging phenotypes such as frailty and cognitive decline.

Chronological age is not your destiny. Biomarkers like DNA methylation (epigenetic clocks) show that your body's biological state can differ significantly from your birth year. While you cannot change your birth date, these markers suggest that your health trajectory is influenced by factors like inflammation, immune function, and lifestyle. Monitoring these biological ages (where available) may offer more insight into your health risks than age alone, highlighting the importance of maintaining metabolic health and managing inflammation to potentially slow biological aging.

Thus far, the most promising, new biological age predictor is the epigenetic clock... The most striking feature of the Horvath and Hannum clocks is their ability to predict all-cause mortality independent of classic risk factors.

Why this rating

Based on large meta-analyses (n=13,089) and multiple independent cohorts, though the paper highlights a lack of longitudinal studies proving causality or modifiability.
