A free radical is an atom or group of atoms that contain at least one unpaired electron. If an electron is unpaired, another atom or molecule can easily bond to it, causing a chemical reaction. Each free radical may exist for only a tiny fraction of a second, but the damage is irreversible.
Free radicals are normally present in the body in small numbers.
Under normal circumstances, the body can keep them in check. However, if there are excessive free radicals present, damage to cells and tissues can occur. Common sources of free radicals to the human body today are cigarette smoke, pollution, pesticides, herbicides, overexposure to the sun, automobile exhaust, and more.
