A newly published study suggests a link between vitamin D deficiency and severity of disease from Covid-19 infection.
... [+]A newly published study by a team of researchers from the Azrieli Faculty of Medicine of Bar-Ilan University in Safed, Israel and the Galilee Medical Center in Nahariya, Israel suggests a link between vitamin D deficiency and severity of disease from Covid-19 infection.the research looked at vitamin D levels in 1,176 patients hospitalized with a positive PCR test result between April 2020 and February 2021 at the Galilee Medical Center.
Patients with a vitamin D deficiency were 14 times more likely to have a severe or critical case of COVID than those with more than 40 ng/mL. In addition, the mortality rate for patients who had sufficient vitamin D levels was 2.3%, compared to 25.6% for patients in the vitamin D deficient group. Those striking differences were found even after the researchers controlled for the patients’ age, gender and history of chronic diseases. And because the vitamin D levels were assessed prior to infection, the study avoids the problem that vitamin depletion might have been due to the virus itself.
Vitamin D has long been recognized for its many health benefits such as promoting healthy bones and teeth, supporting the immune system, and lowering cardiovascular health risks. And during the pandemic, physicians have been advising their patients to take vitamin D because they thought it could help boost their immune systems, despite little direct empirical evidence to back up that advice.
