“Our findings suggest a potential relationship between vitamins D and K at the time of acute COVID-19 and an association with worse disease severity. Interestingly, both vitamin D and vitamin K may display complementary effects on the cytokine storm, thrombosis, and lung damage during COVID-19. Specifically, they display similar inhibitory effects on inhibition of NF-kB and cytokine release, and vitamins D and K appear to work synergistically to help protect against calcification and damage in the lungs.”
