The effectiveness of the method has been scientifically proven at the University of Birmingham.
Scientists at the University of Birmingham in the UK have proven that taking vitamin D with its deficiency can be a way to protect against infection with coronavirus. They found that health workers who isolated themselves after developing symptoms of COVID-19 were more likely to suffer from vitamin deficiency. This is reported in an article published in the medRxiv Preprint Repository. .
The researchers analyzed blood samples of 392 health workers for the presence of antibodies to SARS-CoV-2 and vitamin D. 55 percent had antibodies to coronavirus, and 61 percent had vitamin D deficiency. Those who had a deficiency were more likely to report symptoms such as scrapes, body pain or fever. This indicates that vitamin D deficiency increases susceptibility to the virus.
Earlier, researchers at the University of Boston School of Medicine found that patients with normal blood levels of vitamin D infected with coronavirus have significantly fewer severe cases and fewer deaths. Vitamin D deficiency can help prevent complications such as a cytokine storm.
