Accelerated oxidation speeds up programmed cell death, which determines the longevity of our bodies. Your oxidation rates are the result of the oxidants in your body from energy metabolism, contaminants, and your status of antioxidation nutrients and enzymes.
Pollutants accelerate oxidation, and nutritional antioxidants and enzymes slow it down.
Antioxidants work together and leverage each other. Not only is Glutathione a powerful antioxidant, it facilitates the detoxification and excretion of many oxidizing pollutants and poisons. As we age, glutathione levels decline, although it is not known whether this is because we use it more rapidly or produce less of it to begin with. Unfortunately, if not corrected, the lack of glutathione in turn accelerates the aging process. They go on further to say this about boosting glutathione levels.
