Define the Effect of Deficiency of Vitamin K?

Both excess and low intakes can have serious implications on human health, although such conditions arise rarely, these can often be life-threatening. Our subsequent discussions are pertaining to excess and deficient intake. Adults are usually protected from a lack of vitamin K because vitamin K is widely distributed in plant and animal tissues, the vitamin K cycle conserves the vitamin, and microbiological flora of the normal gut synthesizes menaquinones. Also, a normal diet contains about 300 to 500 mcg vitamin K daily and therefore supplies at least three times the amount of recommended vitamin K. Vitamin K deficiency leads to a lowered prothrombin level and increased clotting time, and thereby haemorrhages.
