Calcium supplementation significantly helps prevent osteoporosis. Osteoporosis occurs when calcium is lost from the bones, making them fragile. By getting enough calcium, you can strengthen your bones and reduce the risk of fractures. You can get calcium from foods like milk, cheese, yogurt, and leafy green vegetables. Additionally, getting some sunlight helps your body produce vitamin D, which aids in calcium absorption. Remember, maintaining healthy habits like regular exercise and quitting smoking is also important.
