Recent Findings on Multivitamins and Ageing
In a significant development in the field of nutritional science, a study published in Nature Medicine has revealed that taking a multivitamin every day for two years appears to slow some markers of biological ageing. This research, funded by the National Institutes of Health, involved 958 healthy participants with an average age of about 70 years, aiming to identify ways to not just live longer, but to live better.
The study’s findings indicate that participants who took a daily multivitamin showed a slowdown in biological ageing for two of the five epigenetic clocks analyzed. This slowdown equated to about four months less biological ageing over the two-year period. Notably, the effects were more pronounced for individuals who exhibited faster biological ageing at the start of the study.
Researchers collected blood samples from participants at the beginning of the trial and again after one and two years to assess the impact of multivitamin intake on biological markers. The study analyzed five epigenetic clocks, which are indicators of biological ageing, to determine the multivitamin’s effectiveness.
However, the beneficial effect of daily multivitamins on biological ageing markers was found to be small. Additionally, the study noted that cocoa extract did not slow biological ageing for any of the five clocks, highlighting the specific impact of multivitamins compared to other supplements.
Dr. Howard Sesso, one of the researchers, emphasized the lack of known risks associated with taking a multivitamin, stating, “There are no known risks for taking a multivitamin in our two large clinical trials.” This statement may encourage individuals considering multivitamin supplementation as part of their health regimen.
Despite the promising results, uncertainties remain regarding the clinical relevance of the findings. As the authors noted, “Ultimately, it is critical to determine the clinical relevance of our findings.” Details remain unconfirmed about who specifically benefits from multivitamins and how these benefits manifest.
Steve Horvath, a prominent figure in the study, remarked, “This is a very interesting and rigorous study,” reflecting the scientific community’s interest in the implications of these findings. The researchers plan to conduct follow-up studies to determine if the slowing of biological ageing persists after the trial ends, which could provide further insights into the long-term effects of multivitamin intake.
As the discourse around multivitamins and their role in health continues, the current study adds a layer of complexity to our understanding of ageing. With ongoing research, the potential for multivitamins to contribute positively to health and longevity remains a topic of keen interest for both scientists and the general public.
