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.
