The cell is the basic structural and functional unit of all known living organisms and is often called the “building block of life.” In the human body, there are five important types of cells. Your body relies on all these cells being healthy to function properly.
A free radical is any atom or molecule that has a single unpaired electron in an outer shell. Free radicals are very unstable and react quickly with other compounds, trying to capture the needed electron to gain stability.
Generally, free radicals attach the nearest stable molecule, “stealing” its electron. When the “attacked” molecule loses its electron, it becomes a free radical itself, beginning a chain reaction. Once the process is started, it creates a cascade, resulting in the disruption of a living cell.
When free radicals overcome our body’s ability to neutralize them, they attack the body itself. As a result, free radicals disturb the action of cellular DNA, which directs key cellular activities. Cells with damaged DNA become stagnant and make the body vulnerable to illness.
Our bodies need antioxidants (such as selenium, vitamin C, and vitamin E) to fight off these free radicals. Antioxidants are reducing agents that limit oxidative damage to biological structures (our bodies' cells) by protecting them from free radicals. Selenium, as a part of our natural enzyme system, is a powerful weapon that prevents free radical production at the cellular level. Many other antioxidants deal with free radicals once they are active, while selenium prevents them from being produced in the first place.
In 1996, the late Dr. Larry Clark of the University of Arizona Cancer Research Center and Dr. G.F. Combs, Jr. published results from the 10-year Nutritional Prevention of Cancer (NPC) Trial. The NPC Trial, which was published in the December 1996 Journal of the American Medical Association (JAMA), showed SelenoExcell, taken as a dietary supplement at 200 micrograms per day, powerfully reduced the risk for certain types of cancer (colon, lung, and prostate) by 50%-63%.
