Wikipedia says that melatonin is one of the most potent antioxidants which can surpass blood and brain barriers as well as cell membranes. This antioxidant does not go through oxidation or reduction repeatedly unlike others. Redox cycling often allows antioxidants like vitamin C work as a pro-oxidant, leading to the formation of free radicals.
Melatonin cannot be brought back to its previous state once it gets oxidized because while getting oxidized, it reacts with the free radicals and forms various end-products. Thus, melatonin is also known as one of the terminal antioxidants.
