For years, we’ve been tracking our biological age through expensive epigenetic tests like TruDiagnostic’s PACE or Horvath clocks.
While these DNA methylation tests are powerful, they’re also costly ($300-500 per test), require specialized labs, and aren’t something most people can access regularly through their standard healthcare.
Enter the Bortz model—a breakthrough biological age calculator published in Nature Communications Biology in October 2023 that achieves something remarkable: it estimates your biological age using just 25 standard blood biomarkers, the same ones your doctor likely orders in your annual physical.
And this is, to me, the most accurate model to date.. Let’s dig in….
