DNA Methylation Clocks Reveal How Fast You're Really Aging
A comprehensive review of 435 studies reveals that DNA methylation patterns serve as powerful biological clocks that can measure how fast you're actually aging compared to your chronological age. Researchers analyzed 167 studies using methylation-based strategies and found these epigenetic markers consistently track biological aging processes. The review shows methylation clocks have evolved significantly, with newer algorithms becoming more accurate at predicting health outcomes and lifespan. These biological age measurements can reveal whether lifestyle factors are accelerating or slowing your aging process, potentially decades before traditional health markers show changes.
