Questions Regarding the Link Between Vitamin D Levels and COVID-19

Study suggests a link between vitamin D deficiency and COVID-19 severity and mortality.

A recent study published by researchers in Israel indicates a correlation between vitamin D deficiency and COVID-19 severity and mortality.

The study was based on the findings from the initial waves of Israel’s COVID-19 outbreak prior to vaccines becoming widely available. The researchers found that patients with vitamin D deficiency were more likely to develop a severe or critical case of COVID-19 compared with those who have sufficient levels of vitamin D in their blood.

The study showed that individuals with vitamin D deficiency were 14 times more likely to develop a severe or critical case of COVID-19. Further, mortality rates for patients with insufficient vitamin D levels was found to be 25.6% versus 2.3% among individuals with adequate vitamin D levels.
