Metabolic bone disease expert weighs evidence
In short, no. Although calcium and vitamin D play an important role, they are not sufficient when used alone. Rather, they should be used in combination with an antiresportive agent such as estrogen, raloxifene, alendronate, risedronate or calcitonin.
In almost all randomized controlled trials of antiresorptive agents, the control groups took calcium and vitamin D supplements. In these trials, patients who took alendronate, risedronate or raloxifene had significantly fewer fractures than those who took calcium and vitamin D alone. Thus, we conclude that supplements alone are not adequate.
Still, calcium and vitamin D are important in treating age-related bone loss, as they reduce the rate of bone loss and possibly reduce fracture risk.
