Study Finds Lack of Popular Vitamin Linked to Severe COVID

( – After two devastating years of COVID-19 infections worldwide, doctors are only now beginning to understand why some patients experience mild cases while others spend weeks in intensive care units or die suddenly. One recently published peer-reviewed study out of Israel may shine some light on the matter.

Dr. Amiel Dror and his colleagues from Bar Ilan University and the Galilee Medical Center conducted the study looking at vitamin D levels in 1,176 patients over a 2-year period before infection by the COVID-19 virus. They found that patients who were chronically deficient in vitamin D (less than 20 ng/ml in blood samples) before infection were more likely to suffer severe disease symptoms and death than patients who weren’t. Typical blood levels of vitamin D are 20-40 ng/ml.

According to the paper’s conclusion, “The use of historical results obtained before the COVID-19 pandemic…enabled us to suggest vitamin D deficiency contributes to the … COVID-19 mortality risk and disease severity.” Their research showed those who were deficient in vitamin D were more than 8 times more likely to die and 14 times more likely to experience severe symptoms.

For years, researchers have noted the importance of vitamin D in bone, brain, endocrine, muscle, and immunological health. It’s a marker of overall good health. People can obtain the vitamin naturally by eating fatty fish, egg yolks, fortified foods, getting sunshine, and taking supplements under a healthcare provider’s supervision. A word of caution: too much vitamin D can be toxic.
