Vitamin K is made up of a number of similar fat-soluble compounds. Vitamin K is essential for the production of proteins involved in blood coagulation. In addition, vitamin K is needed to make proteins that are involved in the health of bones and arteries.
Vitamin K deficiency is a life-threatening condition because without blood clotting we can bleed to death, but it is very rare, mostly occurring when someone has been on a long course of antibiotics or has a fatty liver disease. Vitamin K deficiency is more common in newborn babies.
