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.
Vitamin D is a fat-soluble vitamin, as it is stored in the liver and fatty tissues. It is stored for long periods and is eliminated slowly from the body. Vitamin D is often referred to as the “sunshine vitamin” because the body makes it after being exposed to sunshine. It is the only vitamin that the body can produce on its own, but it needs sunlight to do so. The body must get all other vitamins from diet and/or supplementation. There are several forms of Vitamin D, including D2 and D3. Vitamin D2 is synthesized by plants, and Vitamin D3 is synthesized by humans when their skin is exposed to ultraviolet-B (UVB) rays from sunlight.
