Impact of Multivitamins on Biological Aging
Recent research suggests that taking a daily multivitamin for two years might slow some markers of biological aging. This finding is particularly significant as it indicates a potential method for promoting healthier aging.
The study involved more than 900 healthy participants, with an average age of about 70. Participants were divided into four groups: those receiving a multivitamin and cocoa extract, those taking cocoa extract and a placebo, those on a multivitamin and placebo, and a control group receiving two placebos.
Results showed that individuals who took a daily multivitamin exhibited a slowdown in biological aging for two of five epigenetic clocks, equating to roughly four months less biological aging over the study’s duration.
Despite these findings, several large trials have previously failed to demonstrate meaningful mortality reduction from standard multivitamin supplementation in well-nourished populations. This raises questions about the overall efficacy of multivitamins in promoting health.
The study was published in the journal Nature Medicine and received a grant from Mars Edge, which included the donation of multivitamins for the research. While the results are intriguing, experts caution that the study’s findings are not conclusive.
Dr. Dorsa Jalaei, a lead researcher, stated, “The honest answer, supported by the weight of current evidence, is, for most healthy adults eating a reasonably varied diet, no.” This sentiment is echoed by Professor Pilar Guallar Castillón, who advises against taking multivitamins in any form.
Furthermore, 41 percent of people who take supplements opt for multivitamins, according to research from the Food Standards Agency. However, experts believe that taking a multivitamin may not address the root causes of biological age acceleration.
Dr. Howard Sesso noted, “This study opens the door to learning more about accessible, safe interventions that contribute to healthier, higher-quality ageing.” Yet, Professor Luigi Fontana cautioned that the magnitude of the effect is extremely small and inconsistent across all aging measures tested.
As the scientific community continues to explore the role of multivitamins in health, the long-term effects of supplementation on biological aging remain unclear. Details remain unconfirmed.
