Antioxidants are special compounds that bind to free oxygen radicals, preventing them from damaging healthy cells.
Free radicals are unstable molecules that the body naturally produces as it metabolizes amino acids and fats. They freely react with and destroy healthy cells, and can alter the structure of DNA. Free radicals are commonly associated with oxidative stress that may adversely affect cardiovascular, neurological, skin and visual health.
The body forms antioxidants, such as glutathione,
lipoic acid and
coQ10, to neutralize free radicals. However, the production of antioxidants declines with age.
Vitamin C and
vitamin E are necessary antioxidants that must be obtained from the diet. Additional antioxidants include
vitamin A,
selenium,
lutein,
lycopene, polyphenols and flavonoids (such as anthocyanidins, catechins and quercitin) found in fruits, vegetables and herbals.
Some of the most potent botanical sources of antioxidants include:
- açaí fruit
- bilberry
- grape seed
- olive fruit
- mangosteen fruit
- pine bark
- pomegranate fruit
