How much calcium do you really need? The question is how much of each. Dr. Willett recommends going lower on calcium and higher on vitamin D than the guidelines suggest—500 to 700 mg a day of calcium and 800 to 1,000 IU of vitamin D. At that rate, you can probably get all or most of your calcium from food, especially if you have a serving or two of dairy products daily. If you can't tolerate dairy, you should still be able to get 300 mg a day in your diet and can take a low-dose calcium supplement to make up the rest. By keeping your supplement consumption to 500 mg or less a day, you should avoid the possible risk of heart disease and kidney stones suggested by the studies.
