Tiny Edge Against Aging Markers Found in Daily Multivitamins, Study Says
In a 2-year randomized trial of 958 older adults (average age ~70), daily multivitamin–multimineral supplements modestly slowed increases in two DNA-based aging clocks (PCPhenoAge by ~2.6 months, PCGrimAge by ~1.4 months); cocoa extract had no effect. The benefit was larger for those with faster baseline aging. Limitations include a largely homogeneous sample and the small magnitude of effect; epigenetic clocks are preliminary biomarkers, so more diverse, longer studies are needed to determine if these changes affect health or lifespan.
