Vitamin K comes from the word "Koagulation" in German. This vitamin is a fat-soluble vitamin that is mainly required for blood coagulation. Vitamin K plays an important role in blood coagulation, but there are also several other factors that are involved in the coagulation process as well. Vitamin K is also important in bone metabolism and vascular health.
Many countries inject newborn babies with vitamin K. This is because vitamin K is also a prophylactic that is capable of preventing hemorrhagic disease or HDN. This disease is due to a vitamin K deficiency and the injection provides a vitamin K supplement shortly after birth in case the child has this condition.
