Do you know your vitamin D level? If not, getting your blood tested—and optimizing your levels—is one of the simplest and most straightforward steps you can take to improve your health, including in relation to COVID-19. Vitamin D, as an immunomodulator, is a perfect candidate for countering the immune dysregulation that’s common with COVID-19.
As early as November 2020, it was known that there were striking differences in vitamin D status among people who had asymptomatic COVID-19 and those who became severely ill and required intensive care unit (ICU) care. In one study, 32.96 percent of those with asymptomatic cases were vitamin D deficient, compared to 96.82 percent of those who were admitted to the ICU for a severe case.
