Forty-one interventions proven to reverse epigenetic aging in humans

Epigenetic aging, determined by DNA methylation patterns, has emerged as the central measure of true biological aging speed. A systematic analysis of 41 human studies revealed that interventions as varied as regular exercise, plant-rich diets, semaglutide (a metabolic-control pharmaceutical), caloric restriction, omega-3 fatty acids, and multivitamin supplementation effectively reduce epigenetic age as measured by next-generation clocks—models that correlate more strongly with mortality risk than earlier versions. However, not all interventions proved effective: nicotinamide riboside, rapamycin, and senolytics showed no detectable change, while plasmapheresis accelerated epigenetic aging. Though these clocks remain investigational biomarkers with recognized limitations (they don't capture all aging mechanisms, such as accumulated DNA mutation damage), they offer biohackers and clinics a measurable tool to evaluate which of these interventions genuinely shifts individual biological pace.
