The resulting drop in
glutathione production and intracellular
glutathione concentrations compromises the mitochondria's ability to scavenge reactive oxygen species (ROS), producing a vicious cycle that drives the progressive
increase in ROS - mediated structural damage and its corollary, the progressive decline in energy production and repair that accompanies aging.
This causes a decrease in intracellular
glutathione (GSH) and a corresponding
increase in ROS (H2O2, O2 --RRB-
concentrations that further upregulates the insulin - independent insulin receptor signaling, perpetuating the cycle.

concentration, it is hypothesized that practically everybody experiences sooner or later an ageing - related deficit in the body cysteine and
glutathione reservoirs that warrants cysteine supplementation.
Studies in animals and humans have shown that dietary
glutathione increases blood levels of
glutathione, but one study in mice suggested that under ordinary conditions, dietary
glutathione can not boost its own
concentration in other tissues except in the lung, where large amounts of
glutathione are needed to maintain the fluidity of mucus.
