Calcium supplementation does help reduce the risk of osteoporosis. Osteoporosis is a condition that makes bones weak and brittle, commonly seen in older adults. Calcium is an essential component for bone health, helping to maintain bone density and strength. Besides calcium, vitamin D is also crucial as it aids in calcium absorption. To prevent osteoporosis, it is important not only to take calcium but also to maintain a balanced diet, exercise moderately, avoid smoking, and limit alcohol intake. If you are at risk for osteoporosis, it is best to consult a doctor who may recommend additional bone density tests and professional advice.
