Adults age at different rates, and past assumptions on aging were largely based on population studies. Recent bioscience advancements allow us to estimate biological age by examining epigenetic biomarkers tied to specific phenotypes. These methods offer deeper insights into healthspan beyond chronological age.

While lifestyle's role in health and aging has long been known, recent epigenetic research now measures cellular and genetic health over time. Accelerated aging links to increased pro-inflammatory and interferon activity and reduced DNA repair, mitochondrial efficiency, and protein synthesis.

To slow aging, reducing inflammation and interferon stimulation helps protect cells and genetic integrity. This research, led by Drs. M. Levine (Yale) and S. Horvath (UCLA), highlights key pathways in aging.

A simple blood test using common lab markers reveals DNA methylation patterns, reflecting biological age. This tool offers ongoing insights into holistic health and the impact of lifestyle choices on epigenetic health.
