| Popis: | THE consistent loss of bone with age is due to inadequate calcium intake, inadequate calcium absorption or excessive excretory loss, or a combination of these problems. The Institute of Medicine recommends that postmenopausal women should ingest 1,200 mg of calcium daily (1). However, the usual daily intake of calcium for 5O--70-year-old American women is about 600 mg/day (2). Fifty-five percent of these estrogen-deprived women have insufficient absorption to maintain calcium balance at an intake equal to 800 mg/day (3). Nearly one fourth would still be in negative balance at an intake of 1,500 mg/day (3). In spite of the poor absorption and bioavailability of calcium in postmenopausal women, taking calcium supplements seems to be the most convenient, easy, safe, and inexpensive way to achieve the requirement and to help prevent or treat osteoporosis. Calcium supplements are particularly important for women who do not consume a sufficient quantity of dairy products or calcium-rich foods to meet their daily calcium needs. This review will summarize the recent clinical studies of the effects of calcium supplements on bone mass in postmenopausal women, discuss the factors that may influence the effectiveness of calcium supplements in preventing bone loss, and report the safety of calcium supplements. |
