Excess free radicals can easily overwhelm your body's natural antioxidant defense systems, wreaking havoc on your athletic endeavors and, more importantly, your health. Antioxidants neutralize free radicals, but merely taking some vitamin C and E won't cut it. You need as much antioxidant support as possible from a wide variety of sources.
