Much research has recently focused on how antioxidant vitamins may reduce cardiovascular disease risk. Antioxidant vitamins — E, C and beta carotene (a form of vitamin A) — have potential health-promoting properties. Though the data are incomplete, up to 30 percent of Americans are taking some form of antioxidant supplement. The American Heart Association doesn't recommend using antioxidant vitamin supplements until more complete data are available. We continue to recommend that people eat a variety of nutrient-rich foods daily from all the basic food groups.
Eating a variety of foods low in saturated fat, trans fat and cholesterol will provide a natural source of these vitamins, minerals and fiber. If you take in more antioxidants through food and supplements, there are a few benefits that you’ll have, with the first being cell protection. Antioxidants can help to protect your cells from damage, which helps to fend off diseases. Many times, you can have a lack of vitamins in your body, which will cause you to recover from diseases or injury very slow. If you have the right amount of vitamins and antioxidants in your body, you’ll notice the differences.
The theory behind the use of antioxidants is very good. But study after study has failed to show any measurable benefit from taking antioxidant supplements. So: either the theory is wrong, or the antioxidant supplements available to us just aren't powerful enough. Whatever the explanation, the AHA's advisory statement is sound. There is no good reason, at this point, to spend your money on antioxidant supplements. You can find many different vitamins and supplements that include them, all you need to do is make sure that you are eating right and doing all you can to lead a healthy lifestyle.
