Both vitamin D and calcium play an important role in maintaining bone health, and their functions in the body are interrelated. Maintaining normal levels of these in the body ensures good bone density, which in turn reduces the risk of fractures in the elderly population.

Calcium and Vitamin D are the two most important nutrients for bone health at all stages of life. Maintaining adequate levels of these nutrients in the diet ensures that bones stay strong and reduces the risk of fracture in the elderly. As we age, an imbalance occurs between the amount of new bone formation and bone breakdown, which leads to a disease called "Osteoporosis" (weak and porous bones). Adequate calcium and vitamin D supplements are the cornerstone of osteoporosis treatment.
