Calcium supplementation can help alleviate osteoporosis but cannot completely cure it. Osteoporosis is a condition where bone density decreases and bone structure weakens, making fractures more likely. Calcium can increase bone density and help make bones stronger, but it should be combined with other treatments, such as vitamin D, exercise, and medication. If you are at risk for osteoporosis, it is recommended to consult a doctor to create a comprehensive treatment plan.
