Vitamin K deficiency and covid-19
Summarizing, the results of this study suggest that vitamin K deficiency is frequently observed in COVID-19 patients and that the deficit is greater in males than in females. In addition, in male patients, vitamin K deficiency is associated with a greater IL-6 level in the general circulation. In conclusion, we propose that vitamin K deficiency could support both cytokine storm Th2 by increasing proinflammatory cytokines such as IL-6, which is involved in the building up of the inflammatory response recruiting both cellular and humoral components.
