What are examples of endogenous antioxidants?

There are five extremely powerful endogenous antioxidants. They are: Glutathione (GSH), Alpha Lipoic Acid (ALA), Superoxide Dismutase (SOD), Catalase and Coenzyme Q10 (CoQ10). Unfortunately, the body’s production of endogenous antioxidants declines as we age.

What are antioxidants that protect against cancer?

The theory of oxygen-free radicals has been known about fifty years ago (4).

Why are antioxidants good for cancer patients?
