Vitamin K is needed by the liver to make certain blood-clotting factors, so if somebody is deficient in the vitamin then they may bleed very easily. Dietary vitamin K comes from green vegetables, although under normal circumstances the body can produce as much as it needs - it's synthesized by the 'healthy' bacteria which live in the large intestine; but vitamin K deficiency can occur when these bacteria get killed off by antibiotics, or if a person has diarrhoea or is using laxatives and the large intestine gets emptied too quickly for the vitamin to be absorbed.
