Vitamin K is a fat soluble vitamin that helps to protect bones from fracture, calcification of arteries, and helps blood to clot normally. Vitamin K is not a single chemical substance. It is a family of related chemical substances that go by the name of “vitamin K.” It helps the body transport calcium and metabolize into your skeleton. It increases bone mineral density and reduces fracture. It also lowers the risk of liver and prostate cancer.
Vitamin K is best known for its role in healthy blood clotting. It is important for the function of several proteins involved in the blood clotting process. In the blood clotting process, it is important in the product of prothrombin and is required for the body to make four of the body's blood clotting factors, mainly prothrombin and the factors VII, IX, and X.
Sources of vitamin K include spinach, Brussels sprouts, Swiss chard, green beans, asparagus, broccoli, kale, mustard greens, carrots, green peas, and cauliflower. Vitamin K deficiency is rare due to bacteria synthesis in the body.
