Scientists at the University of Birmingham in the UK have shown that taking vitamin D when it is deficient can be a way to protect yourself from coronavirus infection. They found that healthcare workers who became isolated after developing symptoms of COVID-19 were more likely to suffer from vitamin deficiencies.
The researchers analyzed blood samples from 392 healthcare workers for antibodies to SARS-CoV-2 and vitamin D. 55 percent of the people had antibodies to the coronavirus, and 61 percent were vitamin-deficient. However, those with the deficiency were more likely to report symptoms such as aches, body pain, or fever. This indicates that vitamin D deficiency increases susceptibility to the virus.
Earlier, researchers from Boston University School of Medicine found that among patients infected with coronavirus with normal levels of vitamin D in the blood, there are significantly fewer serious cases and deaths. Adequate vitamin D can help prevent complications such as cytokine storms.
