Vitamin D3 to Treat COVID-19Different Disease, Same Answer

Educational Objective
To identify the key insights or developments described in this article
1 Credit CME

Biological activity of vitamin D and its metabolites include, among other properties, potent antimicrobial and anti-inflammatory effects in vitro.1 In animal models, administration of vitamin D metabolites attenuates a variety of acute organ dysfunction, including acute lung injury.2 Observational data from patient cohorts support the potential therapeutic application of these findings.3 Specifically, lower circulating levels of vitamin D metabolites are independently associated with worse outcomes in patients with acute illness, including patients with coronavirus disease 2019 (COVID-19).4
