If there were only one or two types of free radicals negatively affecting our bodies, we'd be able to get by with one, maybe two, antioxidants such as vitamin C and vitamin E. The truth, however, is that there are a number of free radicals, both water-soluble and fat-soluble, which is why a wide variety of antioxidants is necessary. Additionally, not only do antioxidants work on a specific type (or types) of free radical, most-to-all of them work synergistically, supporting, augmenting, and enhancing the effects of other antioxidants. The oft-used saying, "The whole is greater than the sum of the parts" is quite appropriate when talking about antioxidants and how they work in the human body.
