The link between vitamin D and COVID-19 – studies have shown
Several recent studies have looked at the impact of vitamin D on COVID-19. A study of 489 participants found that people with a vitamin D deficiency were more likely to be positive for SARS-CoV-2 infection than people who had a normal level of vitamin D.

Other research has shown high levels of vitamin D deficiency in patients with COVID-19 who suffer from an acute form of respiratory failure. These people had an increased risk of death.
Another study found that of 50 people who had been hospitalized for COVID-19 infection and received a concentrated dose of a type of vitamin D (calcifediol), only one needed intensive care treatment. In contrast, of the 26 people who did not receive calcifediol, 13 needed to be treated in intensive care.
What role could vitamin D play in the prevention and treatment of COVID-19
More research is needed to determine what role vitamin D and vitamin D deficiency might play in preventing and treating the new coronavirus infection.
For example, vitamin D deficiency is common in the United States, especially among people of color. These groups were disproportionately affected by the COVID-19 pandemic. Vitamin D deficiency is also common among the elderly, people who have a body mass index of over 30 (obesity) and people who suffer from hypertension. These factors increase the risk of severe symptomatic forms of COVID-19.
Less promising results
However, in recent years, two clinical trials that have studied the effects of vitamin D supplements have had less promising results. In both studies, high doses of vitamin D were given to people who were deficient and sick (they were not infected with the SARS-CoV-2 virus).
Vitamin D did not reduce the length of hospital stay or mortality rate when the data were compared with people who received placebo, according to MedicalXpress.
What to do if you suffer from a vitamin D deficiency
In the meantime, if you also suffer from a vitamin D deficiency, it would be good to talk to a medical specialist about taking supplements. If you are worried about your body’s vitamin D levels, turn to a specialist who can help you perform a set of tests.
