Osteoporosis is more common in older adults, especially women, after menopause when the body's production of estrogen decreases, which can lead to a decrease in bone density. Adequate calcium intake, along with regular physical activity and weight-bearing exercises, can help to prevent osteoporosis. Adequate calcium intake is particularly important during childhood and adolescence when bones are growing and developing. During this time, the body is building up its bone mass, and a lack of calcium can lead to a lower peak bone mass, which can increase the risk of osteoporosis later in life.

When vitamin D is present, it helps the body to absorb calcium from the gut and also aids in reabsorption of calcium in the kidney. Vitamin D also helps to regulate the amount of calcium in the body by promoting its deposition in bones and preventing its loss in the urine. It's important to maintain a balanced diet rich in calcium and vitamin D and regular physical activity, as well as exposure to sunlight, to help keep bones strong and healthy.
