title: [Calcium supplement and bone metabolism].
abstract: Calcium supplementation ameliorates the elevated bone metabolism, especially for the elderly osteoporotic patients, because, calcium suppresses PTH level through the increase of serum calcium level. Urinary deoxypyridinolin, and/or NTx can detect the metabolic changes induced by calcium supplementation. Serum markers such as serum CTx or NTx will detect the small changes more clearly in near future.
