Calcium is the mineral you have the most of in your body. It makes up the structures of your bones and teeth and helps maintain typical muscle function, blood clotting, cardiac function, nerve transmission, and other body processes. Maintaining these critical functions is not just about increasing your calcium intake. Your body also needs vitamin D to absorb and maintain calcium levels, and vitamin K to maximize the benefits of vitamin D. Both vitamin D and vitamin K are fat-soluble vitamins that play a central role in calcium metabolism. Vitamins D and vitamin K are more effective combined together than alone in exerting their effect on calcium metabolism. Vitamin K helps to maximize the benefits of vitamin D. Vitamin D helps the body absorb and use calcium and vitamin K helps to direct the body to the proper places to store it, like in the bones, teeth and other areas of the body. This is why Nevancia has formulated a supplement with vitamin K, vitamin D, and calcium all together in one serving! Each serving contains 5000 IU (125 mcg) of Vitamin D3, 100 mcg of K2, and 210 mg of Calcium.
