title: [Calcium and vitamins].
abstract: Sufficient calcium intake and vitamin D adequacy are prerequisite for any pharmacological treatment for osteoporosis. The latter has been often ignored in Japan, partly because serum 25(OH)D measurement is not reimbursed by health insurance policy and perhaps because natural vitamin D cannot be prescribed by phySicians in this country. Here, some of the recent metaanalyses of calcium, vitamin D metabolites, and vitamin K on osteoporosis are reviewed. A new vitamin D metabolite, eldecalcitol, will also be discussed.
