Vitamin D supports the body's immune system, muscle function and bone health, and the discovery of new research has given people a reason to supplement vitamin D.
According to a new study by the American Journal of Clinical Nutrition, vitamin D3 is implanted every day to protect DNA in chromatopathy and may significantly prolong aging.
Researchers from Harvard and Georges Hospital (MCG) analyzed Brigham and Women’s Hospital) More than 1,000 people over 50 in the random trial of VITAL found that taking 2,000 IU of vitamin D3 health products per day during the four-year period will help reduce the aging process. Why? This is because vitamin D3 can help maintain the length of telomeres, which are protective caps at the end of the chromatotype, like plastic sleeves at the end of the shoe strap.
The study's lead investigator JoAnn E. Manson pointed out that this discovery is important because if telomeres shorten too quickly or too much, it may accelerate the body's biological aging process.
Although this is not the first study to investigate the potential benefits of vitamin D3 on telomeres, it is the largest and longest random trial in this topic. Here are some more in-depth findings from scientists.
The study lasted for five years and traced 1,054 American adults, including women over 55 and men over 50. Dr. Manson said that the selection of ethnic groups over 50 was because at this age, the risk of chronic diseases began to increase.
Study participants were divided into two groups, one was given to a comfort agent and another was given a daily vitamin D3 (2000 IU) supplement and another omega 3 fatty acid (1 g) supplement.
To test the telomeres length in the participants' white blood cells, the researchers collected the participants' blood at the beginning and drew blood again in the second and fourth years.
At the beginning of the study, the two groups were similar, but in the second year, researchers found that the telomeres shortened by the differences in vitamin D3, and by the fourth year, the difference between the two groups began to become obvious. Compared with the pacifiers, the telomeres shortened significantly, preventing aging of about three years, the omega 3 fatty acid supplement had no real significant effect on telomeres.
What is the possible reason? Dr. Manson explained: "We found that the inflammatory C reactivity protein was reduced when we took the vitamin D3 group. We believe that the effect of hypoinflammatory vitamin D3 may be one of the reasons for the less telomeres shortening."
Manson said the research team was amazed by the research scale. "We expected vitamin D to reduce telomeres shortening, but we did not expect to see such a difference in this issue."
