Vitamin K refers to two fat-soluble vitamins, Vitamin K1 and Vitamin K2. Vitamin K1, or phylloquinone, is made by plants and is the primary source of Vitamin K that humans obtain through food. Vitamin K2, or menaquinone, is typically produced in the large intestine by bacteria; this function is improved with the presence of cultured milk, like yogurt, in the diet. Vitamin K is an essential nutrient necessary for blood clotting and regulating the body’s normal blood clotting process. When there is a skin wound, even a simple cut, the body needs sufficient blood clotting ability to the close the wound and prevent excessive bleeding. On the other hand, blood needs to flow throughout the body freely without forming clots that would block an otherwise functioning blood vessel. Vitamin K is also needed for bone health, as it may reduce bone loss and decrease the risk of bone fractures. It also helps build strong bones, as well as protecting bones from weakening or fracturing. For this reason, Miami dentists encourage patients to maintain a diet that is rich in vitamin K to help strengthen tooth enamel. Holistic dental professionals also believe that diets that are rich in vitamin K help to improve overall oral health.
