You can reduce oxidative stress in the body by gobbling down antioxidants, or by simply reducing pro-oxidant physiology, which reduces the need for antioxidants from nutrition or supplements.
Iron is the ultimate pro-oxidant component in human physiology, and many of us live in an iron fortified world. Iron fortification was started to alleviate anemia in menstruating females, and may work well for this, but for males, who tend to accumulate iron, this can cause problems. Cancer, heart disease, diabetes, Alzheimer's, arthritis, and a host of other conditions have been associated with excess iron. More on this here:

A ferritin blood lab is a cheap and easy way to measure stored iron, and from what I've read ferritin is best kept out of triple digits for optimal health. One can lower ferritin through donation of whole blood (the iron is in the red cells), but for those who can not or will not donate blood, there are other options.
Iron chelators can help with iron homeostasis by mopping up free/labile iron, which is the most dangerous kind. IP6 (Inositol Hexaphosphate), Curcumin and Quercetin are the best known natural iron chelators and are very benign regarding side effects. Some call them antioxidants, as they do reduce oxidative stress, but they do it in a different way than the traditional antioxidants (Vitamin C, E, etc) by heading oxidation off before it starts.
I stumbled upon iron homeostasis by accident as I've been a blood donor since the mid 80s. I've lead an atrocious life of alcohol, tobacco and junk food, but at 60 years of age am still enjoying excellent health. Perhaps I was simply born a genetic superman, and perhaps my luck will run out before I reach 65, but truly believe controlling iron accumulation has saved my health thus far.
My co-workers often think I'm 10 years younger than I actually am, and are astonished when they hear me talking of retirement. I'm naturally slim without exercise, still have a full head of brown hair and have never experienced any form of chronic illness. I have no smokers hack and sprint over the 105 stairs at our convention center to get to the waterfront most every weekend without getting winded.
I often think to myself how odd it is to have discovered the fountain of youth by accident, and unlike Dorian Gray, I didn't even have to sell my soul!
