Osteoporosis is a progressive disabling bone condition where the bones soften as a result of bone resorption exceeding bone formation. Tang et al in a careful review of the prescription of calcium and vitamin D concluded that calcium ( 1200 mg / day ) or calcium plus 800 iu of vitamin D in addition to the calcium significantly and beneficially decreased bone loss and decreased fractures.
