Old people can eat calcium carbonate, which contains high calcium content, so calcium supplementation is usually better. In addition, the elderly can choose calcium tablets containing vitamin D, which is helpful to promote the absorption of calcium, because the absorption of calcium is inseparable from vitamin D, and the elderly should also pay attention to the blood calcium level before taking calcium tablets. If you have hypercalcemia, it is recommended not to supplement calcium casually.

It is more appropriate to supplement calcium tablets for osteoporosis in the elderly, but it is also necessary to rule out osteoporosis caused by secondary causes. Although most elderly people suffer from osteoporosis due to age and physical decline, tumor diseases that are prone to occur in the elderly are also likely to lead to secondary osteoporosis. Therefore, besides paying attention to the level of calcium ion, we should also pay attention to eliminating the primary disease.
