NCT02316925

Brief Summary

A randomized, double blind placebo-controlled parallel intervention in adults over the age of 50 will be performed. Participants will receive a supplement capsule containing placebo (Crystalline Cellulose) or 500mg of Setria® Glutathione to eat for 120 days. Glutathione is hypothesized to replenish the body's reserves that may be depleted through natural aging process, poor diet, or due to the detoxification process for drugs. The primary end point is the number of healthy days experienced during cold and flu season. Secondary endpoints include cellular and biochemical measures from blood samples taken before and after the study.
