Calcium deposited in organs that do not need it can contribute to many medical problems, including arterial narrowing, heart disease, kidney stones, and heel spurs.<\/p>\n<p><strong>Vitamin K2<\/strong> is a fat-soluble vitamin responsible for directing calcium to the right tissues and helping prevent calcium deposition where excess calcium is not needed.<\/p>\n<p>The vitamin was discovered in the 1930s and until recently was mainly known as a clotting factor. Its importance as a calcium regulator in the body has become clearer only more recently.<\/p>\n<p>The main dietary source of <strong>K2<\/strong> comes from animals that feed on leafy forage. During fermentation processes in the animal\u2019s digestive system, K2 is formed.<\/p>\n<p><strong>The link between vitamin D and vitamin K2<\/strong><\/p>\n<p>There is a close functional relationship between vitamins D and K2.
