Calcium is vitally important its true, but it must be plant based to be utilized by the body. The calcium in most mineralized water and in supplements is nothing but ground rock and the body cannot utilize it. The best thing a person can use while working on improving their diet is a good superfood green powder. With it you get the minerals in a form that the body can use plus a lot of other good stuff. Once you discover the right diet for your body at its present stage of health, you can get your vitamins and minerals from whole foods. Pure water and fresh whole foods are the ideal. If supplements are used, make sure they are of the type the body can use, if not you will be a ticking time bomb for problems in the future. Rock minerals can cause hardened and narrowed blood vessels, including blocked capillaries that will result in damaged and starved cells that cannot get necessary nutrients. Kidney stones, cataracts, high blood pressure and constipation also can result from consuming large amount of rock minerals.
