Small-molecule free radical scavengers and trace elements Vitamin D exerts its antioxidant effects by counteracting the activity of NADPH oxidase, which is responsible for ROS production [32]
Studies associate higher glutathione levels with improved psoriasis symptoms
As the primary factors for the reduced anticancer effect 1) the reduced delivery and uptake of the anticancer agent, 2) the need for the conversion of molecular oxygen (O 2 ) into reactive oxygen species (ROS), 3) the preferred therapeutic effect against highly proliferating cells, which is reduced under hypoxic conditions, or 4) adaptation of the cancer cells by promoting cell survival and upregulating certain resistance pathways, has been suggested 1,2,3,4,5
