Scientists say a daily multivitamin may help slow aging

A daily multivitamin may help slow biological aging, according to researchers studying older adults in a large clinical trial. After two years, participants taking multivitamins showed slower aging in several DNA-based epigenetic clocks, with the effect equal to about four months less biological aging. People who started out biologically older than their actual age appeared to benefit the most. The findings hint that a simple supplement could play a role in healthier aging.
