Vitamin D might be doing more than just supporting bone health — it could also help the body age slower, according to a new study led by researchers at Mass General Brigham (MGB) and the Medical College of Georgia. The study, published this month in The American Journal of Clinical Nutrition, reveals that taking vitamin D supplements may protect againstbiological agingby slowing the shortening of telomeres, the tiny caps on DNA that naturally erode as people grow older. Conducted as part of a nationwide four-year trial, the study tracked over 1,000 U.S. adults (men over 50 and women over 55) and found thatdaily vitamin D3could reduce biological wear and tear, equivalent to nearly three years of aging, according to a press release from MGB. Colorectal Cancer Risk Reduced By This Common Vitamin, Study Suggests Participants were randomly assigned to take either a placebo or a daily dose of vitamin D3 (2,000 IU) and omega-3 fatty acids (1 gram). Telomere length in white blood cells was measured at the start of the study, at the two-year mark and after four years. Read On The Fox News App Compared to the placebo group, those taking vitamin D3 had significantly less telomere shortening, the researchers found. In contrast,omega-3 supplements"had no significant effect on telomere length throughout follow-up," the team reported. Aging May Speed Up In Areas With Extreme Heat, Research Suggests This was the first large-scale, long-term randomized trial to show that vitamin D supplements protect telomeres, according to co-author JoAnn Manson, M.D., the Michael and Lee Bell Professor of Women's Health at Harvard Medical School. "This is of particular interest because VITAL (the trial) has also shown benefits of vitamin D in reducing inflammation and lowering risks of selectedchronic diseases of aging, such as advanced cancer and autoimmune disease," Manson said in the release. Telomeres act like protective tips at the ends of chromosomes, similar to the plastic ends of shoelaces, according to the researchers. They "prevent chromosome ends from degrading or fusing with other chromosomes." Over time, theseDNA capsshorten, which is a natural part of aging and is linked to a higher risk of age-related diseases. Because of this, scientists view telomere length as a marker of "biological age," which may better reflect a person'shealth statusthan their actual age in years. Earlier phases of the trial showed that vitamin D supplementation could reduce inflammation and lower the risk of certain chronic age-related conditions, such asadvanced cancersand autoimmune diseases, Manson noted.

"Our findings suggest that targeted vitamin D supplementation may be a promising strategy to counter the biological aging process, althoughfurther researchis warranted," said first author Dr. Haidong Zhu, a molecular geneticist at the Medical College of Georgia, in the release. The research team emphasized that more work is needed to determine how vitamin D impacts aging in different populations and whether these effects endure over longer timeframes.
