Common daily vitamin could delay biological aging, suggests a significant study

Vitamin D could be more than supporting bone health, it could also help the slower body age, according to a new study led by General Mass Brigham researchers (MGB) and the Georgia Medical College.

The study, published this month in the American Journal of Clinical Nutrition, reveals that vitamin D supplements can be protected against biological aging by slowing down the shortening of telomeres, the tiny DNA caps that naturally erode as people age.

It was performed as part of a four-year national essay, the study monitored more than 1,000 American adults (men over 50 and women over 55) and found that Vitamin D3 daily could reduce biological wear, equivalent to almost three years of aging, according to a statement from MGB.

Participants were randomly assigned to take a placebo or a daily dose of vitamin D3 (2,000 UI) and omega-3 (1 gram) fatty acids.

The length of the telomer in white blood cells was measured at the beginning of the study, at the two -year mark and after four years.

Compared to the placebo group, those who took vitamin D3 had a significantly less shortening of telomeres, according to researchers.

Instead, Omega-3 supplements “had no significant effect on the telomer length during the entire follow-up,” the team reported.

This was the first large -scale and long -term random essay that showed that vitamin D supplements protect telomeres, according to co -author Joann Manson, MD, women’s health professor Michael and Lee Bell at Harvard Medical School.

“This is of particular interest because vital (trial) has also shown benefits from vitamin D in reducing inflammation and decreasing risks of chronic -selected chronic diseases, such as advanced cancer and autoimmune disease,” Manson said in the statement.

According to researchers, telomers act as protection tips at the ends of chromosomes, similar to the plastic ends of the shoes. “They prevent the ends of the chromosome from degrading or merging with other chromosomes.”

Over time, these DNA caps are shortened, which is a natural part of aging and is related to a higher risk of age -related diseases.

Due to this, scientists see the duration of the telomer as a marker of “biological age”, which can better reflect the health status of a person than their real age for years.

Why does it matter?

The previous stages of the trial showed that vitamin D supplementation could reduce inflammation and reduce the risk of certain conditions related to chronic age, such as advanced cancers and autoimmune diseases, said Manson.

Although new telomeres find does not show that vitamin D slows down through the table, researchers say it is a potentially powerful way to protect the body at the cellular level.

“Our results suggest that Directed Vitamin D supplementation can be a promising strategy to counteract the process of biological aging, although more research is required,” said the first author, Dr. Haidong Zhu, molecular geneticist at the Georgia Medical College, in the statement.

Previous research suggests that vitamin D could reduce inflammation and reduce the risk of some age -related diseases.

The research team emphasized that more work is needed to determine how vitamin D affects aging in different populations and if these effects last longer.
