Vitamin K

Vitamin K is a fat-soluble vitamin, so the body stores it in fatty tissue and the liver. Vitamin K is best known for its role in blood clotting. The “K” comes from the German name, Koagulationsvitamine. Besides buying vitamin K pills, there are also many foods that contain a lot of vitamin K, such as beef liver, green tea, turnip greens, broccoli, kale, spinach, cabbage, asparagus, and dark green lettuce. Chlorophyll, for example, is the substance in plants that gives them their green color and provides vitamin K.
