Glutathione ​​is one of the important substances confirmed by modern science to be able to remove free radicals that affect human health. Western medical experiments have determined that free radicals are one of the main causes of aging and disease. The most abundant and important component in the human cell system is Glutathione, which regulates the effects of foreign antioxidants such as vitamins C and E.

    In 1956, Professor Harman first proposed the theory of free radicals. He found that fisherman who works under strong sunlight for a long time have a short life. Further research proved that ultraviolet rays can stimulate the production of free radicals in the body, and free radicals promote the aging of the physiological cycle as well as death phase. Free radicals are produced during the metabolism of human cells. They can attack proteins, DNA, and lipid macromolecules in cell membranes, destroy the physiological functions of these biological macromolecules, make cell membranes hard, brittle, and eventually lose function. It also shortens the life span of cells, cause cell membranes to form voids, therefore, vulnerable to pathogens and viruses invasion. Free radicals can further damaging the nuclear membrane, and as a result, genetic materials are exposed and damaged, which would lead to mutation and low immunity.

    Under normal conditions, Glutathione can convert unstable molecule into a low-active substance, therefore reducing the negative impact in the body. However, with the increase of age, the human body's ability to produce Glutathione reduces to a degree that it becomes difficult to remove unstable molecules in the human body in time, which affects the body's operating efficiency. In addition, external factors such as ultraviolet radiation, drinking, smoking, environmental pollution, certain drugs, etc. can also cause excessive external damage to the human body. These external factors increase the demand of Glutathione for the human body, in order to maintain the normal function.

    Increasing the effective content of Glutathione in the cells is the most powerful way to enhance system functionality. Many countries have a large number of literatures on clinical application of Glutathione and have done research on medical and health care applications as well.
