There are several probable ways that IP6 exerts its effects:
(1) Antioxidant Protection through Chelation: Antioxidants are believed to fight cancer because they prevent free radical damage to DNA. Unbound iron (ferritin), though not a free radical itself, can be the catalyst for the deadly Fenton Reaction, in which iron reacts with the relatively harmless hydrogen peroxide (H2O2) and forms the highly reactive hydroxyl radical (OH.). IP6 chelates free iron, thereby preventing the hydroxyl radical production before it starts.
