Calcium is an important trace element in human body and has important physiological functions. However, if calcium is excessive, it will do great harm to human body, so we suggest that calcium should be supplemented scientifically.

First, eating too many calcium tablets may lead to urinary calculi. Urinary calculi are harmful to human body, easy to recur and difficult to cure.

Second, it can also produce anorexia, nausea, constipation, indigestion and other effects, thus affecting the intestinal absorption of nutrients such as iron and zinc, resulting in secondary trace element deficiency.

Third, it may also cause hypercalcemia, which will seriously lower blood pressure, affect heart function, increase the risk of heart disease in the future, and aggravate arteriosclerosis.

Fourth, too much calcium supplementation in children may lead to premature calcification of bones and premature closure of epiphysis, thus affecting bone development.

Therefore, it is suggested that you must pay attention to the appropriate amount of calcium supplementation, not as much as possible, and make reasonable calcium supplementation according to the doctor's advice and instructions.
