Are biological age tests worth it?
Grade: Promising
“A consumer 'biological age' test tells you how fast you're aging.”
Epigenetic clocks and pace-of-aging measures are a genuine and active research field. As a consumer product, a single result is interesting but noisy — it's a snapshot with real measurement variability, not a diagnosis.
If you find the number motivating, fine. Just don't let it override the basics: the interventions in the next chapters matter far more than the score.
Grade: Promising. Use it as a curiosity and a nudge, not an authority. On the companion site's Get-Tested page we lay out which tests are research-grade vs consumer-grade.
This is one row of the report card.
Look 40 at 60 grades every major intervention on the strength of the evidence — and ties each grade to its sources.
