Abstract
Chronically sick elderly women had low intakes and low blood concentrations of vitamin C. Small dietary supplements of vitamin C increased the concentration of vitamin C in their plasma and leucocytes to those found in both the active elderly and the young. These findings confirm that low concentrations of vitamin C in the institutionalized and chronically sick elderly are primarily due to poor intake and can be easily corrected by dietary changes. The case for increasing the intake of vitamin C in these patients is discussed.
