Sepsis and septicemiaHow does vitamin D work?

Vitamin D may reduce the risk of sepsis by enhancing the body’s innate immune system

Vitamin D fights bacterial and viral infections through induction of cathelicidin12 and defensins3

Cathelicidin and related compounds have been shown to combat bacterial infections and their toxic products in animal models45.  Cathelicidins can be considered antisepsis molecules6
