Scientists talked about the effects of vitamin D on health and life expectancy

Vitamin D is essential not only for bone health, but also for preventing chronic diseases, strengthening the immune system, and reducing mortality. This is stated in a study published in the MPDI journal, which Izvestia reviewed on August 12.

The authors of the report noted that current clinical guidelines are mainly focused on protecting the musculoskeletal system, while underestimating the wide range of beneficial effects of vitamin D on the body. A review of scientific evidence has shown that this nutrient helps maintain immune function, reduces the risks of cardiovascular diseases, a number of oncological pathologies, type 2 diabetes, cognitive impairment, and complications during pregnancy.

The paper summarizes the results of large cohort studies indicating that vitamin D levels above 30 ng/ml (75 nmol/L) are associated with a significant reduction in the likelihood of developing serious diseases and mortality. At the same time, a significant proportion of the population in different regions of the world has this indicator below 20 ng/ml, which requires measures to increase it.

According to scientists, concentrations above 30 ng/ml can be achieved by taking 2,000 IU (50 mcg) of vitamin D3 per day. For optimal protection against a wide range of adverse outcomes, including reducing the risk of cancer, cardiovascular events, and pregnancy complications, the range of 40-70 ng/ml is preferred, which can be achieved at a dosage of 4000-6000 IU per day.

The report highlights that many large randomized trials fail to identify the benefits of vitamin D due to errors such as participants' initially high vitamin levels or low supplementation doses. This, according to scientists, underestimates the real effectiveness.

In addition, the study recommends integrating data from both randomized and observational studies into future clinical guidelines, paying attention to individual differences in vitamin D intake.

Therapeutic defect: which diseases are dangerous to treat on your own

Doctors told me what's wrong with people who don't seek help from doctors.

Earlier, on July 24, Daria Khaikina, a pediatric endocrinologist at the SM Clinic, said that the benefits of children's vitamins in the form of marmalade are offset by a large amount of added sugar and artificial flavors. They impair the absorption of many vitamins, such as C and D.

Before that, on July 23, the obstetrician-gynecologist of the Center for Reproductive Health of the SM Clinic, Idilia Orfanova, named vitamins for women's health. The doctor noted that vitamins A, C, D and E, as well as folic acid (vitamin B9), will be useful.
