Vitamin D deficiency has emerged as a primary risk factor for severe COVID-19 infection and death. Higher vitamin D levels have even been shown to lower your risk of testing positive for the virus in the first place
According to a Spanish study, 82.2% of COVID-19 patients tested were found to be deficient in vitamin D
One study found your risk of developing a severe case of, and dying from, COVID-19 virtually disappears once your vitamin D level gets above 30 ng/mL (75 nmol/L)
Vitamin D can reduce your risk of COVID-19 and other respiratory infections via several different mechanisms, including reducing the survival and replication of viruses, reducing inflammatory cytokine production and maintaining endothelial integrity
Dark skin color, increased age, pre-existing chronic conditions and vitamin D deficiency are all features of severe COVID disease. Of these, vitamin D deficiency is the only factor that is modifiable. As such, it would be foolish to ignore, especially since vitamin D supplements are readily available and low cost
