Several studies and meta-analysis suggest that vitamin D deficiency constitutes a risk factor for acute respiratory infections while supplementation mayreduce this risk. Given the current context of the COVID-19 pandemic, the role of vitamin D supplementation in the prevention and improvement of theprognosis of affected patients has been suggested by some studies and refuted by others. Through this article, we report the mechanisms of action andproperties of vitamin D, and we discuss the different hypotheses of the involvement of vitamin D in respiratory infections, especially COVID-19 in thelight of the most recent published data.Keywords: COVID-19, SARS-CoV-2, Vitamin D deficiency, Vitamin D supplementation, 1.25-dihydroxyvitamin D.
