Usually they are for oral administration in the form of pills or capsules. However, the absorption of antioxidant enzymes in supplement form is minimal at best. A better way would be to supplement the body with the "building blocks" required in order for our body to manufacture its own SOD, catalase, glutathione peroxidase, and other such antioxidant enzymes. By neutralizing free radicals, antioxidants actually prevent the onset of these diseases and at the same time keep the body healthy and strong. Being natural substances, antioxidants are derived from various plants, including vegetables and fruits. Blueberries and cranberries are usually the fruits that are often touted by nutrition scientists as the top antioxidant rich foods. Perhaps due to this alarming number, much of scientific researches conducted in the US today have recently been focused on how antioxidant vitamins may reduce the risk of cardiovascular disease. Previous studies have shown that antioxidant vitamins, such as vitamin E, vitamin C, and beta carotene (a from of vitamin A), have potential health-promoting properties. With antioxidant supplements still far from the high expectations of the scientific community, you can in the meantime turn to the more reliable source of these helpful compounds, which are antioxidant foods. Below are some examples of antioxidant foods which you can include in your daily diet: Berries The provocative allure, the fragile charm, the rich concentration of nutrients. " Because of their highly unstable nature, free radicals increase damage to cells of the body, thus contributing to the aging process.
