Although oxygen is essential for life, its reactivity with other compounds can be detrimental. Free radicals are the result of some oxygen molecules that are converted into oxidizing agents during the process that creates energy in cells, cellular respiration. Oxygen is a very active element, and in the process of exchanging the molecules in the bloodstream, oxygen combines with many different compounds. Some of the compounds can cause damage to body tissue.

These harmful compounds, "free radicals", can be caused in a number of ways, such as ionized radiation from the sun, x-rays, and industry; nitrous oxide from automobile exhaust, cigarette smoke, alcohol, saturated fat, and chemicals found in food, water, and air. Because of free radicals' instability, they react with cells in the body causing abnormality. There are many free radical related health problems and conditions such as cancer, aging, atherosclerosis, and over 60 identified others.
