The active Vitamin D is required for bone metabolism of the minerals Calcium and phosphorus can be absorbed from food in the gut. Calcium is the most important substance for the curing of the bone responsible. He decides, among other things, about the bone density.
In the case of older people, particularly women, play a variety of factors in the degradation of bone density is a role. Among other things, it is the decreased production of the hormone Estrogen, but also other degradation processes contribute to the formation of porous bone. This is referred to as osteoporosis. Osteoporosis is a dreaded disease, since it leads to an increase in Falls and bone fractures. Doctors see a connection between the Vitamin D supply and the development of osteoporosis. They prescribe Vitamin D for this reason, often as a preventive measure.
