Common daily vitamin shows that it slows the aging process for a period of four years

Previous investigations have linked a common vitamin with a deceleration in aging, and now a new Harvard study seems to confirm those findings.

The study, which was published in the American Journal of Clinical Nutrition, found that taking a daily vitamin D pill prevented the telomeres from shortening, a distinctive seal of aging.

Telomeres, which are often compared with plastic tips at the ends of the laces, act as “protective extremes” in chromosomal threads, according to a Harvard press release.

Common daily vitamin could slow biological aging, suggests an important study

As people age, telomeres shorten, which can increase the probability of poor health and mortality, have demonstrated previous studies.

The research has also suggested that the highest levels of vitamin D in the blood are linked to longer telomeres.

In this last randomized trial, approximately 1,000 people 50 years old or more were divided into two groups: a group took 2,000 international units (IU) of vitamin D pills every day, and the other group took placebo pills.

After a period of four years, people who take vitamin D showed less than half of the shortening of telomeres than the placebo group.

The vitamin D group also had less autoimmune diseases and reduced inflammation markers.

The main author of the study, Joann Manson, professor of Medicine at Harvard’s Faculty of Medicine, said the findings “suggest a promising role for vitamin D in the deceleration of a path for biological aging and chronic diseases related to age.”

While researchers were surprised that vitamin D was linked to such a substantial protection against telomeres, Manson told News Digital, the findings are consistent with previous evidence.

“Vitamin D reduces inflammation, an important cause of telomeres and chronic diseases of aging,” he said.

Vitamin D recommendations

According to Manson, the question of what constitutes an adequate blood level of vitamin D is a “controversial theme.”

In the study, the team found that 2000 IU per day was “very safe”, without side effects or adverse events.

“Blood levels for deficiency and recommended blood levels vary between organizations, laboratories and countries, which is one of the reasons for the doubt about the usefulness of the test,” Manson said.

The US Preventive Services Working Group and most professional societies in the US.

“Vitamin D claims inflammation, an important cause of shortening telomeres and chronic aging diseases.”

“The National Academy of Medicine recommends 600 IU of vitamin D per day for adults up to 70 and 800 IU above 70 years, stating that these intakes will meet the requirements of the vast majority of adults in the population,” he said.

“However, recent guidelines of endocrine society suggest that vitamin D supplements can be useful for adults over 75 years, babies and children, pregnant women and those with a diagnosis of prediabetes, but do not specify a specific dose.”

For anyone who has concern to obtain adequate vitamin D of their diet and/or time outdoors, Manson said that supplementation with 1000 to 2000 IU/day of vitamin D would be “very reasonable.”

“In the US, foods such as dairy products, cereals and orange juice are often fortified with vitamin D, so verifying nutritional labels can help you make better decisions about what food to buy,” he advised.

“Fatty fish, such as salmon, sardines and tuna, and wild fungi are other sources.”

Groups with a high risk of vitamin D deficiency include those living in nursing homes, people with juggling conditions such as Crohn or celiac disease, those that are treated by osteoporosis or other bone health problems, and those with greater dietary restrictions, such as seriously lactose intolerance, according to Manson.

“[People in these groups] I should talk to your doctors about being tested for vitamin D levels and take a vitamin D supplement, “he recommended.

The doctor said that people only need small amounts to moderate vitamin D for good health, since the metabolism of vitamin is “closely regulated” in the body.

“More is not necessarily better, and the very high doses, as more than 10,000 IU/D, can be associated with high levels of blood calcium or urine and toxicity,” he warned.

Manson emphasized that taking a supplement is not a substitute for a nutritious diet and a healthy lifestyle.

“Although it is much easier to make a pill than to be physically active outdoors and eat healthy, these lifestyle factors will do more to keep it healthy and less their risk of cardiovascular disease, cancer, type 2 diabetes and other chronic aging diseases,” he said.

“More is not necessarily better.”

Going to a 15 -minute walk several times a week at noon will generally provide sufficient exposure to sunlight so that the skin synthesizes vitamin D, Manson added.

“Even more important for your health, it would be outdoors, such as walking, jogging or practicing sports.”

Looking forward to future investigations

“Although the results are exciting, we believe that the replication of these results in a separate randomized trial will be important before changing the general guidelines for vitamin D intake,” Manson said.
