Extra zinc for elderly leads to less infections

55 Healthy seniors received a supplement of 45mg zinc (gluconate) daily or a placebo. In this study that lasted a year the susceptibility to infections, zinc levels, oxidative stress and factors that leads to infections were monitored. At the start of the study the subjects had low zinc levels and a negative oxidative stress and infection profile compared to a control group which consisted of young people.

After 12 months all these factors had shown improvement in the group that was receiving the zinc supplements. Remarkable was also that there was significantly less instances of colds and other infections in the zinc group compared to the placebo group.
