Vitamin D-3 (1000 IU) with Vitamin K-2 (45 mcg)
Vitamin D-3 contributes to normal absorption and utilization of calcium and phosphorus
Vitamin K contributes to the maintenance of normal bones
Vitamin C contributes to collagen synthesis and normal bone function
Now® Vitamin D-3 K-2 is a dietary supplement designed to support bone and joint health.
Vitamin D is a fat-soluble vitamin found in two molecular forms: cholecalciferol (Vitamin D-3), produced in the skin, and ergocalciferol (Vitamin D-2), of plant origin. Vitamin D-3 is the most bioavailable form of vitamin D for the human body.
Vitamin D plays a key role in maintaining adequate blood levels of calcium and phosphorus by promoting their intestinal absorption, thus supporting bone mineralization.
The MK-7 form (Menaquinone-7) of Vitamin K-2 is derived from chickpea fermentation and is allergen-free. While vitamin K is well known for its role in normal blood clotting—being essential for hepatic synthesis of prothrombin (factor II) and other clotting factors—evidence shows it also contributes to bone health and prevents inappropriate soft tissue calcification. It activates osteocalcin, which is thought to be critical for proper bone mineralization. Supplementation with Vitamin K-2 has been shown to reduce fracture incidence and slow the rate of bone mineral density loss.
Calcium fixation is important, but it’s essential that it doesn’t occur in undesired tissues such as blood vessels. Recent studies have shown that Gla proteins—also activated by vitamin K—can inhibit vascular calcification and may even reverse it, restoring arterial flexibility.
Thus, Vitamins D and K work synergistically.
People taking oral anticoagulants should not take vitamin K supplements, as it antagonizes the effects of these medications. A healthy gut is essential for normal vitamin K production, and its synthesis can be impaired by the use of laxatives or antibiotics. Since both vitamins D and K are fat-soluble, avoiding a high-fat diet helps ensure their proper function.
