What is the function of vitamin K? Vitamin K is essential for the proper coagulation of blood and prevention of bleeding by means of a blood coagulation factor called prothrombin. A sufficient intake helps reduce nosebleeds and bruising. In addition to this, the vitamin appears to significantly lower the risk for both liver and prostrate cancer and has important anti-inflammatory properties. Last, but not least, vitamin K helps prevent bone loss, bone fractures as well as arterial calcification.
Vitamin K deficiency symptoms: easy bruising, heavy menstrual bleeding, nosebleed, bleeding gums, bleeding occurring in the digestive tract, excessive bleeding in general, calcification of blood vessels (also known as arterial calcification) and heart valves, frail bones and bone fractures.
