Calcium supplements and bone health

By Jennifer K. Nelson, R.D., L.D. and Katherine Zeratsky, R.D., L.D. August 21, 2010

Calcium supplements have long been considered a safe complement or replacement for dietary calcium. But recently a report came out saying that people who take calcium supplements are at greater risk of a heart attack.

Don't throw away your calcium supplements yet. There's more to the story. The results of this particular study are not conclusive and, thus, not sufficient to dictate a change in recommendations about calcium supplements for otherwise healthy people.

If you're not meeting your daily calcium requirements with low-fat dairy and other calcium-containing foods, then a calcium supplement may help. (It's a good idea to talk to your doctor or a registered dietitian if you have concerns about taking dietary supplements.)

But a diet rich in calcium is only part of maintaining bone health. The best prescription for healthy bones also includes:

  • Getting enough calcium in childhood to reach peak bone density.
  • Performing weight-bearing exercise, which helps bones stay strong.
  • Getting enough vitamin D. Your body needs vitamin D to absorb calcium.

Did this media report make you rethink your use of calcium supplements? If so, what are your plans for protecting your bone health?

To your health,
