* '''Non-enzymatic Antioxidants:''' This group includes Vitamin C, Vitamin E, and glutathione. These small molecule antioxidants scavenge free radicals and contribute to the repair and regeneration of oxidized antioxidants. | * '''Non-enzymatic Antioxidants:''' This group includes Vitamin C, Vitamin E, and glutathione.

* '''Metal-Binding Proteins:''' Proteins such as ferritin and ceruloplasmin that sequester free iron and copper ions, which can catalyze the production of free radicals, thus reducing oxidative stress. | * '''Metal-Binding Proteins:''' Proteins such as ferritin and ceruloplasmin that sequester free iron and copper ions, which can catalyze the production of free radicals, thus reducing oxidative stress. | ||
