antioxidantsSubstances that inhibit oxidative changes in molecules. Many oxidative changes are destructive and this applies as much to the human body as to non-biological chemistry. Recognition that many of the fundamentally damaging processes in disease are oxidative in nature and result from the action of oxygen FREE RADICALS has raised interest in the possibility of using antioxidants to minimize such damage. The most popular choice for this purpose are the antioxidant vitamins C and E. There is evidence that, taken in adequate dosage, these vitamins act synergistically to reduce free radical effects.

Patient discussion about Antioxidants
Q. What are “antioxidants”? and what do they do? I’ve been hearing about antioxidants for quite some time now, they are supposedly help to keep us younger. What do they do and is it true?
A. When every biological system works- it creates oxidants. These are materials that are very active and they “look for” something to react with. So when you eat (an example) there are a lot of oxidants created. they move around in the colon and they usually react with colon cells, thus destroying them. This also happens while breathing, cell metabolism and a lot of biological processes. Antioxidants counteract these free oxidants and stop their harmful reaction.More discussions about Antioxidants
