Glutathione known as the master antioxidant is essential in the body’s detoxificati on process and to prevent free radical damages to healthy cells. As we age and constantly being burdened with free-radical damage caused by viruses, bacteria, heavy metal toxicity, radiation, medications and unhealthy stress, our body’s ability to produce glutathione decreases. This depletion leads to depressed immune function and increased vulnerability to infection, inflammation and diseases.
