Daily multivitamin slows ageing markers in older adults, study suggests
A two-year, randomized COSMOS trial found that taking a daily multivitamin slowed certain epigenetic clocks of ageing in people around 70, reducing biological age by about four months versus non-users; the effect was more pronounced in individuals with accelerated ageing and was observed in two of five DNA methylation clocks linked to mortality risk. While promising, the authors emphasize the effects are small and do not yet imply improved clinical outcomes.
