Supplementation of 45mg elemental zinc for a period of 12 months in elderly persons who had low baseline zinc levels, the infection rate seen with supplementation (29%) was lower than placebo (88%) although upper respiratory tract infection rates trended to be less common (50% reduction) but this failed to reach significance.
