Calcium is an essential mineral for the human body. Many people do not get enough calcium on a daily basis. 99% of calcium is found in our bones and teeth. Calcium is a necessary building material to "build" strong teeth and thicker bones when we are young, but also to keep our bones in the best possible condition as the years go by, to avoid unpleasant consequences. Calcium supplements not only strengthen bones and teeth, but also act against osteoporosis, reduce the risk of cancer, control stress and calm the nerves.
