An Israelian study found a direct association between low vitamin D levels and an increased risk of COVID-19 infections. In this study, the data of 7807 participants were used. Participants were tested on COVID-19, and blood samples were used to measure vitamin D levels. Participants who tested positive on COVID-19 had a significantly lower vitamin D level than participants who tested negatively. This means that people with a lower vitamin D level are more susceptible to COVID-19 infections. Additionally, low vitamin D levels increased the risk for hospitalization.
