[Vitamins and trace elements in the elderly (author's transl)].

A review of published research data on the requirement, intake, and signs of deficiency of vitamins and trace elements in old age is presented. It particularly deals with the problem of a general indication for vitamins and trace element supplements - the mean components of geriatric preparations. Special emphasis is laid on the question if these substances exhibit a specific effect on the alterations of physical and psychic capacity typically accompanying the growing old. It could be shown that in several groups of the elderly diminished vitamin levels are common and/or vitamin and trace element intake does not reach daily recommended allowances. But it still remains unclear if these findings have to be considered as disease symptoms.
