    Women have been told for decades to take calcium supplements after menopause, but these supplements could be doing more harm than good. Learn more on the safety of calcium supplements in this video of Dr. Oz, Dr. Corey Hebert, Dr. Donnica Moore, and Dr. Janet Taylor.

    If your diet is inadequate in calcium, a supplement may be necessary. However, when it comes to calcium supplements, some may be good but more is not better.

    The upper level for calcium has been set at 2,500 milligrams daily to avoid hypercalcemia (hyper = too much; calcemia = calcium in the blood) or too much calcium in the blood, subsequent impaired kidneys, and calcium deposits in the body.

    Too much dietary calcium can also cause constipation and interfere with the absorption of other minerals, such as iron, zinc, magnesium, and phosphorus. If your diet is inadequate in calcium, a supplement may be necessary, but be careful not to consume too much.

    You should speak with a registered dietitian to determine IF and HOW MUCH of a supplement you should take. You can find a registered dietitian at:www.eatright.org.

    Calcium supplements have been linked to heart disease, so it is better to get extra calcium from your diet than to rely on a pill.

    If you are going to take calcium supplements chronically (whether it's via an antacid or other supplement product), vitamin D should also be supplemented.
