Research conducted by scientists at Brigham and Women’s Hospital suggests that taking a daily multivitamin may help slow biological aging. The findings, published in Nature Medicine, indicate that this simple dietary supplement could have a positive impact on health and longevity among older adults.
The study is part of the larger COSMOS trial, which ran from 2014 to 2020 and involved 21,442 participants with an average age of 72. Participants were assigned to take either a daily multivitamin, a cocoa extract supplement, both, or a placebo. Their health was monitored over several years to assess the long-term effects of supplementation.
The latest results focus on a subset of approximately 1,000 participants who provided blood samples throughout the study. Researchers aimed to measure the effects of multivitamins on biological aging through five different “epigenetic clocks,” which analyze changes in DNA patterns linked to aging.
Among those taking the multivitamin, the study found a significant slowdown in two biological aging markers: PCPhenoAge and PCGrimAge. Specifically, participants experienced an average decrease of 2.6 months in PCPhenoAge and 1.4 months in PCGrimAge compared to the placebo group. Notably, individuals who showed signs of faster aging at the start of the trial benefited the most, experiencing greater delays in their biological clocks.
Howard Sesso, an associate director in the division of preventive medicine at Brigham and Women’s Hospital and a co-author of the study, emphasized the importance of these findings. “Living longer is one thing; living better is just as important,” he stated. Previous research from the COSMOS trial has already indicated cognitive benefits, with participants in the multivitamin group showing improvements in memory equivalent to a three-year delay in age-related decline.
Despite these promising results, researchers stress that further investigation is necessary to determine the broader implications of slowing biological aging through supplementation. The COSMOS trial primarily focused on older adults, leaving questions about the effectiveness of multivitamins for younger populations.
“There is still much to understand about how improvements in biological aging translate into real health benefits,” Sesso noted. Still, the robust design of the COSMOS study lends credibility to its findings, setting it apart from other research in the field.
In addition to cognitive enhancements, the COSMOS trial has also suggested that daily multivitamin use may reduce the risk of certain diseases, including lung cancer. These results support the notion that multivitamins could play a role in preventing chronic conditions and extending healthy years of life.
Looking ahead, the research team plans to continue exploring data from the COSMOS trial and other studies on dietary supplements. They advocate for further clinical research testing how various lifestyle or pharmaceutical interventions might influence biological aging.
As scientists work to unravel the complexities of aging, this latest research offers a glimmer of hope for those seeking to maintain their health in later years. The findings raise the possibility that simple daily actions, such as taking a multivitamin, could contribute to a healthier, longer life.
