Taking vitamin D supplements can reverse the clock of biological aging, the study suggested.
According to clinical trials, adults who take vitamins every day have reduced age -related damage to DNAs related to diseases, including Alzheimer’s and cancer.
Taking vitamin D for four years has been found to prevent almost three years of aging.
Research published in the study US Clinical Nutrition Journal1,054 adults aged 50 and over participated. They received a placebo or vitamin D pill.
Scientists used regular blood tests to measure the length of the participants’ telomeres. age.
The study said, “If you take vitamin D3 supplements compared to taking placebo, telomeres have been greatly reduced over four years.
The authors said the supplements are “prominent strategies to cope with biological aging,” and can help reduce the risk of various diseases, including dementia.
About one out of five British people do not get enough vitamin D.

Telomeres are caps of DNA sequences found at the end of chromosomes. They are compared with the protective plastic tips at the end of the shoelace.
• How to get good age -without fear, turmoil or fashion
During our life, telomeres are shorter, so DNA is no longer protected, so cells can no longer be divided and updated. This is associated with cancer, heart disease, Alzheimer’s and weakened immune systems.
The trial of VILIT was led by a team of Mass General Brigham, a research center for Harvard University. Joann Manson, a senior researcher, said, “It is the first large and long -term random test that shows that vitamin D supplements protect telomeres and preserve telomeres.
Manson said: “This is especially important because VITAL showed the benefits of vitamin D to reduce inflammation and lower the risk of chronic diseases such as immune diseases.”
Participants were administered every day 2,000 IU or 50 micrographic vitamin D3s.
The author of this study, Haidong Zhu, said: “According to our research, the target vitamin D supplement may be a promising strategy to fight the biological aging process, but it is necessary.”
Previous research found that taking vitamin D can lower the risk of dementia.
The body produces vitamin D as a direct sunlight of the skin outdoors and is found in foods such as oily fish and red meat. Most people get the vitamin D levels needed during the summer, but NHS advises everyone to take it every day in autumn and winter.
• Is vitamins D, B12 and magnesium sufficient?
If you are highly risk of deficiency, such as soft or house bounds, it is recommended to take supplements every year. About one of the five British people has a low vitamin D level. NHS says that every day is enough for 10 microgram.
Vitamin D supports many functions of the body, including immune response and healthy bone maintenance.
