title: Vitamin supplementation in the elderly: a critical evaluation.
abstract: Routine vitamin supplementation for the elderly has been advocated by many. Specific vitamin deficiencies are rare in free-living elderly, but are not uncommonly encountered in hospitalized and institutionalized patients. Deficiency may result from interactions with medications or overall poor dietary intake. Low blood or plasma vitamin concentration is not necessarily indicative of a deficient state. Specific vitamin supplements are useful in the treatment and prevention of a deficient state. However, there is little, if any benefit from supplementation for reasons other than replacement therapy. The incidence and clinical symptoms of thiamine (vitamin B1), riboflavin (B2), pyridoxine (vitamin B6), vitamin B12, C, D, folate, niacin, vitamin A, E, beta carotene, and K deficiency and their treatment and prevention in the elderly are discussed.
