Possible Role of Vitamin D3 in the Prevention of COVID-19 Infection and Mortality

Abstract

Despite many efforts around the world to control the outbreak of COVID- 19 virus, this issue has become a pandemic. According to the latest research on the global spread of COVID- 19, researchers have found that adequate vitamin D3 increases resistance to viral infections, reduces the severity of symptoms of the disease, and ultimately mortality rate. However, the results are still contradictory. There are receptors in the human body called ACE2. The COVID- 19 virus can enter the body by binding to these receptors, and the symptoms of the disease develop gradually. Meanwhile, vitamin D3 can attach to these receptors and prevent the corona virus from attaching to the body’s organs. Thus, people who have lower levels of vitamin D3 absorbed during this epidemic should take vitamin D supplements to maintain an optimal level of 25 (OH) D in the blood. Randomized controlled trials and large population studies should be conducted to evaluate these recommendations. There is insufficient evidence between level of vitamin D3 intake and mortality rate of COVID-19 in patients. This review summarizes some of the latest findings about the role of vitamin D3 in COVID-19 infections, severity, and mortality.
