Daily Multivitamin Linked to Slower Biological Aging in Seniors
A two-year, randomized analysis of 958 older adults found that daily multivitamin use slowed biological aging by about four months across five epigenetic clocks, with greater benefit for those who were biologically older at baseline. The study, part of the COSMOS trial and funded in part by Mars Edge and Haleon, does not prove a longer lifespan and experts caution that more research is needed. Diet quality and a balanced diet may be more impactful in general, and multivitamins can be costly or give a false sense of security. FDA regulation concerns and potential nutrient overdosage were noted, with a recommendation to prioritize real food for most people.
