It is a well-known fact that vitamin D performs several important functions, from boosting immune health to regulating blood pressure. Over the past decade, multiple studies have also provided evidence that taking vitamin D could reduce the odds of developing infections like the common cold and the flu.
Given these precedents and the ongoing pandemic, scientists are now eager to determine if vitamin D could also help protect against COVID-19, the disease caused by the Wuhan coronavirus. In a recent study, researchers from Ireland and the U.K. looked at the prevalence of vitamin D deficiency in European countries with varying severity of COVID-19 infection and found a significant correlation between vitamin D levels and COVID-19 risk and death rates.
