Osteoporosis patients should supplement more calcium and vitamin D. Calcium is a crucial part of bones and helps keep them strong. Dairy products, leafy green vegetables, and nuts are rich in calcium. Vitamin D helps the body absorb calcium, and sunlight is the best source of vitamin D, but it can also be found in fish and fortified foods. Additionally, protein is important for maintaining bone health; good sources of protein include lean meats, eggs, and legumes. Proper nutrition combined with moderate exercise can effectively prevent and improve osteoporosis.
