Calcium supplements are usually only required where dietary calcium is inadequate and are best taken apart from food to avoid a phosphate-binding action (see guidance in Treatment of low electrolytes - summary).  Those at risk of osteoporosis should maintain an adequate intake of calcium and vitamin D and any deficiency should be corrected by increasing dietary intake or taking supplements.
