    It seems not a single day passes that I don't learn something new about this unique hormone (mis)named "vitamin D." \nFrom its humble beginnings recognized only as the factor responsible for bone maturation (with deficiency leading to childhood rickets), vitamin D now commands a recognized role in almost every conceivable aspect of health and disease. \n

    The vitamin K2 story, though still preliminary, is becoming increasingly interesting from the perspective of CT heart score reduction. The origin of this concept came from some unexpected observations. One, the observation that osteoporosis (lack of bone calcium that leads to fractures) arises from deficiency of vitamin K2. Two, deficiency of K2 leads to unrestrained calcium deposition in animal models, leading to heart attack in just weeks.

    Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.

    Vitamin K has been known as the coagulation vitamin, because of its role in the blood-clotting process. However, research over the last few decades has shown that the role of K Vitamins - and natural Vitamin K2, the menaquinones, in particular - has been greatly expanded. Of note, K Vitamins activity outside the liver is required for calcium utilization, the key factor in maintaining both bone and cardiovascular health.\n\nVitamin K2 helps to activate vitamin K-dependent proteins responsible for healthy tissues. In bone, it activates osteocalcin, a protein required to bind calcium to the mineral matrix, thus strengthening the skeleton. In circulation, Vitamin K2 participates in carboxylation of Matrix Gla Protein (MGP), the most potent inhibitor of arterial calcification known, lowering the risk of vascular damage.

    The vitamin K dependant protein osteocalcin may have a positive effect on reducing obesity and diabetes, suggests a new study with mice.\nResearchers writing in the journal Cells studied the effect bone cells have in energy regulation, and found that osteocalcin plays a key role in regulating insulin activity.
