Calcium: Too Much of a Good Thing?
Women who consume a lot of calcium and take dietary supplements may be at greater risk of dying prematurely than those get less, a large Swedish study found. The researchers tracked 61,000 women over 19 years, documenting their diet, use of supplements, and health. Women getting 1,400 milligrams or more of calcium per day were more likely to die from any cause and from heart disease during the study than women consuming 600 to 999 mg a day, the authors reported. Women consuming high amounts of calcium from a combination of supplements and food were worse off than those who got all their calcium from dietary sources. The U.S. government recommends that women between the ages of 50 and 71 consume 1,200 mg of calcium per day.
