A daily vitamin D supplement can be the secret to defeating aging.
A fascinating first study study discovered that people who took the 10-cents capsule came to age with much slower speeds.
During the four-year study, participants who assumed vitamin D3 had less damage to their DNA-a sign of slower aging.
It was as if you returned for almost three years of aging compared to those who took a dummy pill, said the researchers affiliated with Harvard.
Since the study was relatively short, the team said that the results were ‘promising’ and that they called to do longer research.
However, they warn the participants in the study three times the generally recommended vitamin D intake.
They took 2,000 international units (IU) every day in pill form, the equivalent of one 3.5 oz portion of salmon.
Although they were still in the safe reach of 4,000 IU or less, experts have warned to take too much vitamin D, build calcium in the blood, leading to vomiting and kidney stones.

Dr. Joann Manson, head of the Division of Preventive Medicine in Brigham and Women’s Hospital, a hospital with Harvard, co-author of the study called Vital.
She said: ‘Vital is the first large-scale and long-term randomized study to show that vitamin D supplements are protecting and retaining the telomer length.
“This is of particular importance because vital had also demonstrated benefits of vitamin D when reducing inflammation and reducing the risk of selected chronic aging, such as advanced cancer and car -immune diseases.”
Wednesday published in the American Journal of Clinical NutritionIn the study, 1,031 adults either saw 2,000 ie vitamin D or a placebo for four years every day.
With the help of blood samples, the team measured the length of the telomers of each person, whereby sequences of DNA repeat that protect chromosomes against damage.
Killing telomeren with age, and previous research shows that people with longer telomeres have a longer life expectancy than people with shorter.
The researchers discovered that telomeres were a maximum of eight times longer in people who took daily vitamin D supplements than those in the placebo group.
Although it is unclear how vitamin D telomeres extends, experts believe that it can help to reduce the risk of DNA-damage oxidative stress and promote the release of enzymes that are thought to make them longer.
The blood tests measured leukocytes telomer length (LTL), the length of telomeres in white blood cells.
Shorter LTL is linked to an increased risk of age -related diseases such as heart disease and cancer.
In the placebo group, LTL fell by 12 percent after two years from the baseline and another 16 percent two years later.
However, those who took vitamin D had only five percent less LTL after two years and two percent less two years later.
The experts estimate the group that used vitamin D, the equivalent of three years of aging prevented from compared to the placebo.
Dr. Haidong Zhu, first study author and molecular geneticist at the Medical College of Georgia, said: “Our findings suggest that targeted vitamin D supplementation can be a promising strategy to combat a biological aging process, although further investigation is justified.”

Although the exact mechanism is unclear, the researchers suggested that vitamin D could create higher levels of telomerase, an enzyme that makes telomeres longer.
In addition, vitamin D helps the oxidative stress, an imbalance between disease -fighting antioxidants and harmful free radicals, which attack cells and tissues. Oxidative stress has been shown to be damaged by DNA, so that telomers may be shortened.
Most experts recommend consuming around 600 to 800 IU per day, considerably less than the 2,000 IU used in the study.
Most vitamin D supplements contain between 1,000 and 2,000 IU.
Consuming more than 4,000 IU a day can lead to a dangerous structure of calcium in the bloodstream.
This is because vitamin D normally the body helps to absorb more calcium, which is crucial for maintaining the health of bone and muscle.
Excess vitamin D ensures that the body absorbs more calcium than it needs, causing it to accumulate in the bloodstream and then deposited in tissues in the kidneys, lungs and heart.
This leads to nausea, vomiting, constipation, dehydration, bone pain and kidney stones.
There were various limitations, including the lack of diversity in the sample size, because most participants were white.
The study was partially funded by the National Heart, Lung and Blood Institute, an arm of the National Institutes of Health.
