TL;DR: Epigenetic clocks are revolutionary scientific tools that analyze chemical marks on your DNA to determine your biological age, which is often different from your chronological age. These clocks, based on a process called DNA methylation, are the most accurate biomarkers of aging we have. They can predict your risk for chronic diseases and even … Read more

Split-screen infographic comparing chronological age on a calendar versus biological age shown on a DNA helix with methylation markers

TL;DR: While chronological age measures how many years you’ve been alive, biological age measures how old your body acts at a cellular and molecular level. It is a far more accurate predictor of your healthspan and lifespan. You can measure your biological age using epigenetic clocks and other biomarkers, and more importantly, you can lower … Read more
