Calcium Supplment: To Take or Not to Take?

According to research, taking calcium, with or without vitamin D, appears to modestly increase your risk of a heart attack, and possibly a stroke. Eating more calcium-rich foods doesn’t seem to cause these issues. If you are taking calcium, you may wish to discuss this with your doctor. To look at the full range of treatments for weak bones, see the Consumer Reports information on osteoporosis.

Bottom Line: Reach your calcium needs by consuming calcium-rich foods/beverages.  If you are unsure how to meet your goal contact a registered/licensed dietitian-nutritionist.  Certain individuals may need to take a calcium supplement in order to meet their needs. If this is the case, take no more than 500 mg of calcium at once (this is approximately the upper level that your body is able to absorb at one time.)
