Study: Daily Multivitamin Slows Biological Aging
- A randomized COSMOS analysis published Monday showed daily multivitamins were associated with about four months' less biological aging over two years, based on 958 participants with an average age around 70.
- Researchers used five epigenetic clocks including second-generation models to analyse DNA methylation biomarkers in blood samples from the COSMOS trial randomization into four pill groups.
- Measured by specific clocks, PCPhenoAge slowed aging by about 2.6 months and PCGrimAge by about 1.4 months, while participants with accelerated biological age at baseline saw PCGrimAge slow by about 2.8 months.
- Experts caution that effect sizes are modest, and Sesso said, 'Rather, this is starting to provide the connecting dots', advising decisions be made with healthcare providers.
- Researchers plan follow-up analyses to see whether clock changes persist and link to clinical outcomes such as cognition, cancer or cataracts, Yanbin Dong, MD, Ph.D., said; if validated, daily multivitamins could be a cost-efficient intervention with small cancer-risk reductions over 10 years.

How to live longer: Daily supplement could shave four months off biological age in two years
Consuming a daily multivitamin supplement over two years may delay the biological ageing process by approximately four months, according to new findings.New research published in Nature Medicine examined changes in DNA methylation patterns, which serve as markers of biological age rather than chronological age.Biological age reflects the condition of one's body, whereas chronological age measures how long someone has been alive.These DNA modific…

Daily Multivitamin May Slow Biological Ageing, Study Suggests
Can a simple daily multivitamin slow down ageing? A new study suggests it might—though the effect appears modest and scientists are urging caution.Researchers from Mass General Brigham found that taking a multivitamin every day for two years slightly slowed certain markers of biological ageing. Unlike chronological age—how many birthdays you’ve had—biological age reflects how well your body’s systems are actually functioning.The study, published…
A startling study has been published in the journal Nature Medicine. According to the study, a common multivitamin tablet has the ability to slow down aging. But how big is the effect – and how do you actually measure “biological aging”? DN's science reporter Johan Nilsson finds out what's going on.
