Oxidant, by definition, is an oxidizing agent, while antioxidant is any substance that acts to slow or prevent the oxidation of another chemical. In the human body, oxidative damage has been implicated in many of our modern day diseases such as cancer, heart disease, and diabetes. Antioxidants, on the other hand, act to tame the free radicals (or highly reactive chemicals) in the body that have potential to harm cells and cause disease.
