For elderly people, it is recommended to intake between 1000 to 1200 milligrams of calcium daily. This helps maintain bone health and prevent osteoporosis. Besides calcium supplementation, it's also important for elderly people to ensure adequate vitamin D intake, as it helps the body absorb calcium better. Including calcium-rich foods like dairy products, leafy greens, and beans in your diet, and getting moderate sunlight exposure to boost vitamin D synthesis are good practices.
