Not sure if it's the best source, but any brightly colored vegetable has antioxidants. The brighter, the better.

An antioxidant is a chemical that reduces the rate of particular oxidation reactions in a specific context, where oxidation reactions are chemical reactions that involve the transfer of electrons from a substance to an oxidising agent.

Antioxidants are particularly important in the context of organic chemistry and biology. All living organisms maintain a reducing environment inside their cells, all cells contain complex systems of antioxidants to prevent chemical damage to the cells' components by oxidation. These antioxidants include glutathione and ascorbic acid and are substrates for enzymes such as peroxidases and oxidoreductases.

A diet containing polyphenol antioxidants from plants is required for the health of most mammals, since plants are an important source of organic antioxidant chemicals. Antioxidants are widely used as ingredients in dietary supplements that are used for health purposes such as preventing cancer and heart disease. However, while many studies have suggested benefits for antioxidant supplements in laboratory experiments, several large clinical trials have failed to clearly demonstrate a benefit for the formulations tested, and excess supplementation may be harmful. It is logical to assume that a one dimensional approach to dietary supplementation with one specific antioxidant is not a panacea, since a broad diet rich in phytonutrients will yield thousands of different polyphenol antioxidants available for metabolism.
