While a small amount of glutathione comes from our diets, most is produced in the body from individual amino acids derived from protein

In particular, the cystine/glutamate antiporter (System X c ), glutathione peroxidase 4 (GPX4) and glutathione (GSH) (System X c /GSH/GPX4 axis) plays a key role in preventing lipid peroxidation-mediated ferroptosis, because of which could be inhibited by blocking System X c /GSH/GPX4 axis
