Researchers working to unpick whether daily multivitamin results in people staying healthier as they age

Taking a multivitamin every day for two years appears to slow some markers of biological ageing – albeit to a small degree, research suggests.

While chronological age is based on how long a person has lived, biological age reflects the state of the body. Estimates of the latter are often based on changes in patterns of DNA methylation – modifications to DNA that accumulate with age and affect how genes function.
