Can vitamin D supplementation prevent complications of the coronavirus infection 2019 (COVID-19) infection?

Abbreviation: Vitamin D deficiency increases the progression of COVID-19, and vitamin D deficiency is more common in older people with a BMI of 30 or more.
According to the National Institutes of Health and the World Health Organization, there are insufficient data
to recommend the use of vitamin D to prevent or treat the virus that causes COVID-19.
Several recent studies have reviewed the effects of vitamin D on COVID-19. One study involving 489 people found that
who had vitamin D deficiency, the test for the virus that causes COVID-19 was more positive than in people who had normal levels of vitamin D.
Other studies have shown severe vitamin D deficiency in people with COVID-19 who have experienced acute respiratory failure.
These people were at significantly higher risk of dying. A small, randomized study showed that of the 50 people hospitalized with COVID-19,
who received a high dose of vitamin D (calcifediol) required only one treatment in the intensive care unit. In contrast, among the 26 people
patients with COVID-19 who were not prescribed calcifediol 13 had to be treated in the intensive care unit.
In addition, vitamin D deficiency is common in the United States, especially among Spaniards and blacks. COVID-19 disproportionately affected these groups.
Vitamin D deficiency is also more common in the elderly, people with a body mass index of 30 or more (obesity) and people
who have high blood pressure (hypertension). These factors also increase the risk of severe symptoms of COVID-19.
However, in recent years, two randomized clinical trials investigating the effects of vitamin D supplements
had less promising results. In both studies, high doses of vitamin D were given to people
vitamin D deficient and severely ill with non-COVID-19. Vitamin D did not reduce their length of hospital stay or mortality compared with those taking placebo.
Further research is needed to determine the role that vitamin D and vitamin D deficiency may play in the prevention and treatment of COVID-19.
In the meantime, if you are deficient in vitamin D, talk to your doctor about whether a supplement may be right for you. If you are worried about vitamin D levels, talk to your doctor.
