Antioxidants slow or prevent the oxidation of other molecules. They are found in many different kinds of foods and can also be taken in the form of supplements. When molecules start to oxidize, they produce free radicals. This process can damage biological reactions and the cells too. Antioxidants
serve to absorb this oxidation. They also contribute to the molecule redox process as a reducing agent. A reducing agent is a substance that causes another substance to undergo reduction, while becoming oxidized in the process.
The most common antioxidants include vitamin A, vitamin C, lutein, carotenoids, lycopene, vitamin E and selenium. These are dietary substances and can be found in foods as well as supplements. The antioxidants that are most important to the body's needs are found in natural foods such as fruits, vegetables, grains and nuts.
