New Research Suggests Daily Multivitamins May Help Slow Aging
Recent studies from Mass General Brigham in Boston suggest that taking a daily multivitamin may help slow the biological process of aging. Published in the journal Nature Medicine, the research indicates that participants who consistently took a multivitamin over two years experienced a slowdown in biological aging by approximately four months.
Biological aging refers to how fast our bodies age at the cellular level—a concept that often differs from one’s actual age in years.
The study involved nearly 1,000 healthy adults, with an average age of 70. Participants were divided into four groups: one group received a multivitamin with a cocoa extract, another received just the cocoa extract, a third group was given a multivitamin with a placebo, and the last group received a placebo only.
Researchers monitored blood samples from these individuals at three different points during the study, focusing on five specific markers, known as “epigenetic clocks,” which measure changes to DNA related to aging.
Dr. Marc Siegel, a senior medical analyst, explained that aging at the cellular level can be influenced by changes in DNA methylation—a process where some cells show decreased markers while others show increases. Those in the multivitamin group showed improvements across all aging markers, particularly benefiting individuals whose biological age was older than their chronological age.
Senior study author Dr. Howard Sesso highlighted the significance of these findings, emphasizing the growing interest in not just living longer but also living better. He expressed excitement about the link between multivitamin intake and measures of biological aging, paving the way for more accessible and safe methods to promote healthier aging.
While the results are promising, Dr. Siegel noted that further research is necessary to pinpoint which specific elements within the multivitamin are contributing to the aging slowdown. He speculated that a variety of vitamins and minerals—from biotin to vitamins B, C, and D—could play a role.
However, the study did have its limitations. The effects of slowing biological aging were modest, and it remains unknown how these changes may influence actual health outcomes. Additionally, the research largely consisted of older adults of European descent, making it difficult to generalize the findings to diverse populations.
Looking ahead, researchers plan to investigate whether the benefits of multivitamins continue post-trial and how they might affect broader clinical outcomes, such as cognitive performance and cancer risk.
The study, funded by the National Institutes of Health, sheds light on the potential health benefits of daily multivitamin use, aiming to better inform those who take them without fully understanding their effects. Scientists are eager to explore these findings further to improve our understanding of biological aging and health in older adults.
