"One theory is that by slowing the rate of biological ageing, it may be possible to prevent or mitigate age-related illness, meaning people have more years of good health. A study carried out by researchers in the US and including funding from the confectionery manufacturer Mars suggests a daily multivitamin could help slow some markers of biological ageing – although what that means in terms of health remains unclear."
"Dr Howard Sesso, a epidemiologist at Mass General Brigham department of medicine and senior author of the work, said the findings did not mean all older adults must take multivitamins. There are no known risks for taking a multivitamin in our two large clinical trials. At the same time, we do not know for sure who benefits, and how, he said."
"Ultimately, it is critical to determine the clinical relevance of our findings, the authors wrote. While a large study published last year found daily multivitamins did not help people to live any longer and might actually increase the risk of an early death, Sesso and colleagues said their previous work had suggested daily multivitamins were associated with improved cognition, and reductions in lung cancer and cataracts."
Research indicates that taking a daily multivitamin for two years may modestly slow certain biological aging markers, specifically changes in DNA methylation patterns that accumulate with age. Biological age differs from chronological age by reflecting the body's actual condition. A US-based study involving 958 healthy participants averaging 70 years old examined whether multivitamins could slow aging markers. Participants received either multivitamins with cocoa extract, multivitamins with placebo, placebos with cocoa extract, or dual placebos. While findings suggest potential benefits, researchers emphasize uncertainty about clinical relevance and who specifically benefits. Previous research linked multivitamins to improved cognition and reduced lung cancer and cataracts, though other studies found no longevity benefits.
