What is the recommended daily calcium intake for adults over 50 to support bone density?

✓ Accepted answer

Adults over 50 generally need between 1,000 and 1,200 milligrams of calcium daily, with specific targets varying by age and sex to effectively maintain bone mineral density.

• Age-Specific Targets: The recommended daily allowance is typically 1,000 milligrams for men and women up to age 70, increasing to 1,200 milligrams for women over 70 and men over 70 to counteract accelerated bone loss.
• Food Sources: Dietary guidelines from the National Health Service and US experts suggest prioritizing dairy products, canned fish with edible bones like sardines, fortified plant milks, tofu, almonds, and prunes to meet these needs naturally.
• Calcium Limits: Limiting calcium to the recommended upper limit of 2,000 milligrams per day is crucial, as excessive intake can increase the risk of kidney stones and interfere with the absorption of other vital minerals like iron and zinc.
• Vegetarian Options: For vegetarian diets, ensuring adequate calcium intake through a variety of plant-based foods and fortified alternatives is essential, as these diets are nutritionally adequate if properly planned to prevent long-term deficiencies.
• Complementary Nutrients: Adequate protein intake, specifically 1.0 to 1.2 grams per kilogram of body weight, and Vitamin D are necessary to support the osteoblasts that build new bone, working in tandem with calcium for optimal skeletal health.
