Antioxidants provide protection for the cells and tissues of the body. They function by defending against free radicals. Free radicals are a by - product of the functioning body. As the body metabolises and uses oxygen, a small amount of this oxygen gets loose and produces free radicals. Environmental factors such as cigarette smoke and pollution also cause an overload of free radicals. Too many free radicals cause damage to our cells, resulting in disease and accelerated aging.
A combination of different antioxidants works better than taking a single high potency supplement.
