"Epigenetic clocks" and biological-age tests promise to tell you how fast you're aging. This guide explains what they measure, how reliable they are, and how to think about the results sensibly.
The difference between chronological and biological age, what epigenetic clocks and biomarker panels claim, how validated they really are, and a sensible view.
What's inside

For educational purposes only
This guide is educational information about longevity and healthy aging — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor. The science of longevity is evolving, and many "biohacks" and anti-aging products are unproven or over-hyped; no supplement or practice has been proven to extend human lifespan, so be cautious of miracle claims. Talk to your doctor before starting fasting, new supplements, or intense regimens — especially if you have a health condition, are pregnant, or take medication — and remember that supplements are not tightly regulated. It does not diagnose, treat, cure, or prevent any condition. In a medical emergency, call 911.
