Vitamin D may be doing more than simply supporting bone health. It could also help slow down your weight, according to a new study led by researchers at Mass General Brigham (MGB) and Georgia Medical University.
The study, published this month in the American Journal of Clinical Nutrition, reveals that taking vitamin D supplements may be protected. Biological Aging A small cap of DNA that is naturally erode as people age by slowing down telomere shortening.
The study, conducted as part of a four-year trial nationwide, tracked and found over 1,000 US adults (men over 50 and women over 55). Daily Vitamin D3 According to a press release from MGB, it can reduce biological wear and tears, which amount to almost three years of aging.
Research suggests that colorectal cancer risk reduced by this common vitamin
Participants were randomly assigned to take either placebo or vitamin D3 (2,000 IU) and omega-3 fatty acids (1 gram).
The length of leukocyte telomeres was measured at the start of the study, marked in the second year, and at 4 years.
Daily vitamin D3 can reduce biological wear and tear, which corresponds to nearly three years of aging, research finds. (istock)
Compared to the placebo group, people taking vitamin D3 had significantly fewer telomere shortening, the researchers found.
in contrast, Omega-3 supplements “There was no significant effect on telomere length across follow-up,” the team reported.

This was the first large, long-term, randomized trial showing that vitamin D supplements protect telomeres, according to co-author Joan Manson, a professor of women’s health at Harvard Medical School.
“This is particularly interesting because (the trial) also shows the benefits of vitamin D in reducing inflammation and reducing selected risks. Chronic diseases of agingadvanced cancer, autoimmune diseases, etc.,” Manson said in the release.
Telomeres are made from repeated sequences of DNA that act like a protective destination at the edge of a chromosome, similar to the plastic edge of a shoelace. Researchers say. (istock)
Researchers say telomeres act like protective hints at chromosome edges that resemble the edges of shoelaces plastic. They “prevent the edges of chromosomes from decomposed or fused with other chromosomes.”

Over time, these DNA cap It is a natural part of aging and shortening that is associated with a higher risk of age-related diseases.
For this reason, scientists view telomere length as a marker of the “biological age.” Health status than your actual age.
Participants in this study were randomly assigned to take either a placebo or daily dose of vitamin D3 and omega-3 fatty acids. (istock)
Why is it important?
Early in the trial, vitamin D supplementation was shown to reduce inflammation and reduce the risk of certain chronic age-related conditions. Advanced cancer And, an autoimmune disease, Manson pointed out.

Findings on new telomeres have not proven that vitamin D slows aging completely, but researchers say it points to a potentially powerful way Cellular level.
This study concluded that vitamin D can help preserve telomeres. Telomeres are “related to the development of certain diseases” as they decrease with age. (istock)
“Our findings suggest that targeted vitamin D supplementation may be a promising strategy to combat biological aging processes. Further research First author, Dr Haydn Zu, molecular geneticist at Georgia University of Medicine, said in the release.
Previous studies suggested that vitamin D may reduce inflammation and reduce the risk of some age-related diseases.
The researchers emphasized that more work is needed to determine how vitamin D affects aging in different populations and whether these effects can withstand longer time frames.
