- A new study shows that vitamin D supplements can help preserve the length of the protective cap at the end of chromosomes known as telomeres.
- Researchers say that maintaining the length of telomeres can slow down some aspects of biological aging.
- Telomerical length is an important component of healthy aging, but the role of vitamin D is not yet clear.
A new study shows that vitamin D supplements can help slow down some of the biological aging.
The shortening is a natural part of aging, but is related to certain age -related diseases. Among these diseases are cancer of bladder cancer, lungs, kidney and gastrointestinal systems.
“According to our research, target vitamin D supplementation may be a promising strategy against biological aging process, but it suggests that further research is needed. Haidong zhuMD, PHD, the first authors of research and molecular genetics at Georgia Medical School of Augusta University name.
Experts agree that new research is interesting, but there are limitations.
“The telomerical length is protected by vitamin D supplements, but it’s not clear how it is interpreted as a real biological aging.” Marilyn TanMD, a medical associate professor at Stanford University, California, told Healthline. TAN was not involved in this study.
“The current research included only a relatively small number of people, only the telomeres of white blood cells, and did not see the health effects of this telomer change. David CutlerMD, Family Medicine of Providence Saint John’s SAINT John’s Santa Monica. “Therefore, the clinical impacts that can be derived in this study are quite limited.” Cutler was not likely to be involved in research.
Researchers are based on the results based on the results essential Random contrast clinical trials supervised by Boston’s Brigham and Women’s Hospital.
For the study, researchers tracked 1,054 participants to see if vitamin D and omega -3 fatty acids could reduce telomeres and slow biological aging.
The research group included women over 55 years old and men over 50 years old. The researchers have measured the length of telomeres of white blood cells in the second and fourth grade, followed by participants for five years.
Researchers reported that omega -3 fatty acids did not significantly affect telomeres.
But they said that vitamin D3 supplements have prevented the same aging of those who have taken vitamin D compared to those who have significantly reduced telomeres and have been plified.
Experts say that in the process of aging, this slowdown has an important advantage.
TAN said, “Delaying biological aging can improve life expectancy and quality of life and reduce the risk of various diseases.
The health advantage of vitamin D has been promoted in recent years.
Previous studies show that enough vitamin D can help to improve heart health.

Vitamin D is known as “sunlight vitamin.” Because the best sauce is sunlight. Your body creates a vitamin D3 in the cholesterol of the skin when exposed to the sun’s ultraviolet rays.
The best time to make the most of this beneficial sunlight is noon when the sun is at its peak. But experts say that too much sunlight can cause sunlight, eye damage, heat stroke and skin cancer.
There are not many foods that are enough sources of vitamin D, but there are several things. They are as follows:
You can also drink milk strengthened with vitamin D. Some kinds of mushrooms and cheese can be a healthy source of vitamin D.
TAN said that the amount of vitamins needed for people depends on the individual.
“The ideal supplementary amount depends on the standard vitamin D.” “Various factors can affect vitamin D levels and metabolism such as sun exposure, year, geographic position, skin tone, kidney function.”
TAN said, “Solar exposure can increase vitamin D levels, but excessive UV exposure is different health risks. You need to discuss with a medical service provider to know exactly how much vitamin D supplement is needed. “
Cutler said that people with healthy vitamin D are probably not needed.
Cutler told Healthline, “There were many studies related to tens of thousands of people who wanted to record the benefits of vitamin D of healthy adults with normal vitamin D levels, and no benefits were found.”
“There was no document on reducing cancer, reducing cardiovascular disease, increased life, infection protection, or improvement of the result.”
“The most supportive strategy to preserve the length of the telomer is to avoid harmful substances such as exercise, diet, stress management, appropriate sleep and tobacco and alcohol.” “These lifestyle changes do not preserve telomeres, but extensively support healthy aging.”
