Calcium and calcium supplements: Achieving the right balance

Calcium requirements

How much calcium you need depends on your age and sex. Many Americans don't get enough calcium in their diets. These are the daily amounts of calcium recommended for most adults:

  • Ages 19 to 50 years: 1,000 mg a day. The total amount of calcium a day should not be more than 2,500 mg.
  • Ages 51 and older: 1,000 to 1,200 mg a day. The total amount of calcium a day should not be more than 2,000 mg.

If you are pregnant or breastfeeding, talk with your healthcare professional before you take any supplement.
