Vitamin D could work more than supporting bone health – this could also help that the physical age more slowly, according to a new study led by the researchers of mass General Brigham (MGB) and the Georgia Faculty of Medicine.
Study, published this month in the American Journal of Clinical Nutrition, reveals that taking vitamin D supplements can be protected from biological aging By slowing telomers shortening, tiny caps to DNA that naturally erodes how people grow up.
Conducted as part of a four-year trial throughout the country, the study followed over 1,000 adults in the United States (men over the age of 50 and women over 55) and revealed that it was Daily vitamin D3 It could reduce biological wear, which is an equivalent of almost three years of aging, the MGB statement said.
Colorectal risk of cancer reduced by this usual vitamin, the study suggests
Participants were randomly assigned to take placebo or daily dose of vitamin D3 (2,000 IU) and omega-3 fatty acids (1 gram).
The length of telomers in white blood cells was measured at the beginning of the study, on a two -year mark and after four years.
The daily vitamin D3 could reduce biological wear, which is an equivalent of almost three years of aging, it showed the study. (East)
Compared to a placebo group, those taking vitamin D3 had significantly less shortened telomers, researchers revealed.
Opposite that, Omega-3 supplements “He had no significant effect on the length of the telomers during monitoring,” the team reported.
Aging can be accelerated in areas with extreme heat, suggesting research
This is the first large, long-term randomized trial that has shown that the supplements of Vitamin D protects telomers, according to co-author Joann Manson, MD, Professor Michael and Lee Bell for Women’s Health at Harvard School of Medicine.
“This is of particular interest because the vital (testing) has also shown the benefits of vitamin D in reducing inflammation and reducing the risk of selected Chronic aging diseasesAs the advanced cancer and autoimmune disease, “Manson said in a statement.
Telomers are made of repetitive DNA series that act like protective tips at the ends of chromosomes, similar to plastic ends of shoes, according to researchers. (East)
Telomers act like protective tips at the ends of chromosomes, similar plastic ends of shoes, according to researchers. They “prevent the ends of the chromosomes to degrade or merge with other chromosomes.”

With time, these DNA caps Shorten, which is a natural part of the aging and is associated with a higher risk of age -related disease.
Because of this, scientists look at the length of telomers as a “biological age” mark, which could better reflect a man health condition than their real age in the age.
The participants of the study were randomly assigned to take placebo or daily dose of vitamin D3 and omega-3 fatty acids. (East)
Why is that important
Earlier examinations showed that vitamin D supplement can reduce inflammation and reduce the risk of certain chronic conditions associated with age, such as Advanced cancer And autoimmune disease, Manson noted.

While the new Telomer findings do not prove that Vitamin D slows down aging all over the board, researchers say that it indicates a potentially powerful way to protect the body on cellular level.
The study concluded that Vitamin D helps to preserve telomers, which are “associated with the development of certain diseases” when shortening with age. (East)
“Our discoveries suggest that the targeted addition of vitamin D may be a promising strategy for suppressing the process of biological aging, although Further research is Waranted, “said the first author Dr. Haidong Zhu, a molecular geneticist at the Georgia Faculty of Medicine, in a statement.
Previous studies suggest that vitamin D could reduce inflammation and reduce the risk of some ages associated with age.
The research team emphasized that more work is needed to determine that Vitamin D affects aging in different populations and whether these effects endure in longer time frames.
