Tips for Taking Calcium and Vitamin D Supplements

Whether you're getting your calcium and/or vitamin D in food or pills, your body can only absorb so much of it at a time. So it doesn't make sense to take in more than about 600 mg of calcium at a sitting, says Siris.

Heaney agrees.

"If you take in 1,000 mg of calcium in one meal, you might absorb 200 mg of it," he says. "But if you take it in two or three meals, you might absorb 300 mg.''

Whatever supplements you're taking, be sure to check the label.

"They all have different amounts of calcium and D in a serving," says Siris. "If you switch brands, be sure you know how much D you're getting in the new brand."
