What is the recommended total daily calcium intake for most adults at risk of osteoporosis?

• A. 500–800 mg
• B. 1000–1200 mg
• C. 1500–1800 mg
• D. 2000–2500 mg

Answer: (B)

Calcium supports bone density and helps prevent fractures as bones remodel over time, which is especially important for adults at risk of osteoporosis. For most of these individuals, aiming for a total daily calcium intake of about 1000 to 1200 mg provides enough mineral to support bone health without unnecessary excess. This amount can be reached through a combination of dietary sources—such as dairy products, fortified foods, and certain leafy greens—and, if needed, supplements. Try to spread calcium intake across meals to optimize absorption and pair it with adequate vitamin D to enhance uptake. While lower intakes can leave bones more vulnerable to loss, going well beyond 1200 mg daily generally doesn’t yield additional bone benefits and may raise the risk of side effects like kidney stones, so staying in this range is the practical target.
