Daily vitamin D supplements can be a secret to aging.
Fascinating first studies show that those who take 10 centr capsules are older at much slower speed.
In a four -year study, the participants who took vitamin D3s were reduced in DNA.
Harvard researchers are like returning almost three years of aging compared to those who have taken the pills, Harvard researchers said.
Given that this study was relatively short, the team said the result is ‘promising’. They demanded longer research.
But research participants accounted for three times the recommended vitamin D intake.
They are the same as serving about 2,000 international units (IU) every day in the form of a pill and one salmon at 3.5oz.
They were still in a safe range of less than 4,000 IU, but experts warned that if you take too much vitamin D, calcium can accumulate in the blood, leading to vomiting and kidney stones.
Researchers at Mass General Brigham have found vitamin D daily.
Dr. Joann Manson, a Harvard -affiliated hospital, Brigham and Women’s Hospital, is known to have co -authored this study.
She said:
“ This is especially important because life showed the benefits of vitamin D to reduce inflammation and reduce the risk of chronic diseases such as immune diseases. ‘
Published on Wednesday Clinical journalAccording to this study, 1,031 adults took 2,000 IU vitamin D or placebo for four years.
Using a blood sample, the team measured the length of the telomeres of each person, and repeated the DNA sequence protecting the chromosome from damage.
Telomeres have been shortened as they age, and previous studies show that people with longer telomeres have longer life expectancy than shorter people.
The researchers found that telomeres were up to eight times longer among those who took vitamin D supplements every day than placebo groups.
Vitamin D is exactly unclear, but experts believe that it can promote the release of enzymes, which are considered to reduce the risk of DNA damage oxidation stress and to make telomeres longer.
Blood tests measured the length of the Telomerical Telome Telome Mere (LTL) in white blood cells.
Short LTLs are associated with increasing risk of age -related diseases such as heart disease and cancer.
In the placebo group, the LTL decreased 12 % in two years after the baseline, and two years later, it decreased 16 %.
However, people who took vitamin D had 5 % less LTL two years later, and 2 % less than two years later.
Experts estimate that groups with vitamin D will prevent three years of aging compared to placebo.
Dr. Haidong Zhu, the first research author and molecular geneticist at Georgia Medical School, said: ‘According to our research, further research is required, but targeted vitamin D supplements can be a promising strategy to respond to biological aging courses.’
The telomeres depicted here are thought to be protected from the damage. Short telomeres are associated with short life (stock image).
The exact mechanism is unclear, but researchers suggest that vitamin D can make a higher level of telomeric enzymes that can make telomeres longer.
Vitamin D also helps to lower oxidative stress. It attacks cells and tissues between oxidation stress, disease combat antioxidant and harmful free radicals. Oxidation stress has been shown to damage DNA and potentially shorten telomeres.
Most experts consume about 600 to 800 IU a day, much less than the 2,000 IU used in this study.
Most vitamin D supplements include between 1,000 and 2,000 IU.
Eating more than 4,000 IUs a day can lead to risk of calcium in blood flow.
Vitamin D is generally important for maintaining bones and muscle health because it helps the body absorb more calcium.
Excessive vitamin D absorbs more calcium than the body needs, accumulates in the bloodstream, and then calms to the tissue of the kidneys, lungs and heart.
This leads to nausea, vomiting, constipation, dehydration, bone pain and kidney stones.
Since most participants were white, there were several restrictions, including the lack of diversity of sample size.
The study was partially funded by the National Heart and Lung and Blood Institute, the weapons of the National Institute of Health.
