Calcium and Osteoporosis

Medically reviewed by Last updated on Mar 5, 2023.

Calcium is important for osteoporosis because calcium helps build bone mass. Osteoporosis is a long-term medical condition that causes your body to break down more bone than it makes. Your bones become weak, brittle, and more likely to fracture.


Your calcium needs:

  • Women:
    • 19 to 50 years: 1,000 mg
    • Over 50: 1,200 mg
    • Pregnant or breastfeeding, 19 years to 50 years: 1,000 mg
  • Men:
    • 19 to 70: 1,000 mg
    • Over 70: 1,200 mg

Foods that are high in calcium:

The following list shows the number of calcium milligrams (mg) per serving. Your dietitian or healthcare provider can help you create a balanced meal plan for your calcium needs.

    • 1½ ounces of shredded cheddar cheese (306 mg) or part skim mozzarella cheese (275 mg)
    • 1 cup of skim, 2%, or whole milk (300 mg)

How to get extra calcium:

  • Add powdered milk to puddings, cocoa, custard, or hot cereal.
  • Sift powdered milk into flour when you make cakes, cookies, or breads.
  • Use low-fat or fat-free milk instead of water in pancake mix, mashed potatoes, pudding, or hot breakfast cereal.
  • Add low-fat or fat-free cheese to salad, soup, or pasta.
  • Add tofu (with added calcium) to vegetable stir-fry.
  • Take calcium supplements if you cannot get enough calcium from the foods you eat. Your body can absorb the most calcium from supplements when you take 500 mg or less at one time. Do not take more than 2,500 mg of calcium supplements each day.
