Given the role of coagulation in the pathophysiology of COVID‐19, the pandemic sparked an interest in vitamin K. It has been hypothesized that COVID‐19 may precipitate vitamin K deficiency as, theoretically, extrahepatic vitamin K may become depleted if it is utilized to a greater extent for carboxylation of pulmonary MGP and coagulation factors during infection (Janssen et al. 2021). This evidence concerns the gene MGP and COVID-19.
