Antioxidants are natural enemies of free radicals because one of their functions is to break the chain reaction and destroy free radicals. Therefore, while antioxidants can be found in many fresh fruits and vegetables, it still pays to take antioxidant dietary supplement along with your food. Vitamin C antioxidant dietary supplement is perhaps the most famous form of antioxidant available. Some antioxidant fruits may also be taken in dried, powdered forms, like dietary supplements or pills. There is some research though that antioxidant fruits may be taken better if you actually include them in your diet. Fruit, vegetables, and cereals in your diet have additional benefits compared to taking antioxidant fruits supplements. Lead researcher of the Creighton team, Dr. Debasis Bagchi, announced that Activin seemed to exhibit more powerful potential compared to the other antioxidants. "Our studies show that Activin is a more potent antioxidant than vitamins C, E, and beta-carotene - up to seven times more potent," Bagchi said when he reported the findings of their study at the Experimental Biology conference in New Orleans. The building block nutrients of antioxidant enzymes include the minerals manganese, zinc, and copper for SOD and selenium for glutathione peroxidase. In addition to antioxidant enzymes, many vitamins and minerals may also have antioxidant properties. These include vitamins C, E, A (beta-carotene) and nutrients such as lutein, lycopene, vitamin B2, coenzyme Q10, and cysteine (an amino acid). We hear them mentioned all the time whenever there's a new scientific study being released in the American Health Journal or some such explaining how antioxidant juice from berries can aid in liver function or how antioxidant juice from red wine is the scientific reason behind the French paradox. Antioxidants, it seems, have far more benefits than we realize. In fact, Vitamin C might even provide some protection against loss of sight associated with cataracts in older people. So far the most promising of all antioxidant supplements is Vitamin E, especially when it comes to working against heart disease. People who eat more foods rich in Vitamin E tend to have reduced risk of heart disease.
