Vitamin D reduces fracture risk by enhancing bone density and reducing the risk of falling[1, 2].
The effects of vitamin D on muscle strength and falls occur early after 2-3 months , which may
explain early anti-fracture effects of vitamin D. As a large part of the older population, community-
dwelling or institutionalized, have low 25-hydroxyvitamin D levels[4, 5], general vitamin D
supplementation may be warranted. Such a recommendation is possible, for vitamin D
(cholecalciferol) is inexpensive and well tolerated. Results of a recent meta-analysis of high quality
randomized controlled trials indicate that 400 IU vitamin D per day is not enough for fracture or fall
prevention, while a daily intake of at least 800-1000 IU vitamin D may achieve these benefits [1, 6,
7]. A combination of vitamin D with calcium may be important, however the amount of additional
calcium is unclear and may depend on daily intake of calcium from food sources and 25-
hydroxyvitamin D status. An advantage of milk products as a source of calcium is the additional
protein. According to results from fracture studies and data from epidemiologic studies on hip bone
density and lower extremity function , a serum levels of at least 75 nmol/l 25-hydroxyvitamin D
