Uncertain: The optimal daily dose for calcium and vitamin d supplementation is uncertain. 1200 mg of calcium (diet plus supplement) and 800 iu of vitamin d daily is recommended for most postmenopausal women with osteoporosis. Although the optimal intake has not been clearly established in premenopausal women or in men with osteoporosis, 1000 mg total of calcium and 400 to 600 iu of vitamin d is suggested.
