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, do not use this product just for calcium as there may be too much, even toxic, amounts of aluminum and magnesium. Magnesium hydroxide can cause diarrhea and, in patients with kidney failure or on dialysis, lead to a high toxic magnesium blood level. This should be discussed 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.
