Adults need 1500 mg a day and post menopausal females even more. Unless you drink a quart of milk a day, you likely do not get enough calcium from your food. However, for calcium alone, it is best to use the inexpensive calcium carbonate by itself. Constipation can often be corrected by a high fiber diet. Patients with hormone disorders of the parathyroid glands, those on kidney dialysis or who have any calcium problem should discuss its use with the physician.
Antacids are one of mankind's oldest friends.
If you develop occasional heartburn or indigestion, you take an antacid and get instant relief. No house should be without an antacid. Yet, if these symptoms occur daily or several times a day and especially at night, then there could be a more serious problem. These conditions are rarely healed by antacids alone. A specific diagnosis must be made by the physician.
