For instance, it’s not uncommon to hear of someone taking 1,000 milligrams of vitamin C, but that’s about the same amount in 14 oranges. “Vitamins live under this notion that you can’t possibly hurt yourself,” he said. “But you can, by challenging Mother Nature and taking these vitamins and concentrating them to these exceptionally large quantities that you would never normally eat.” Opinion: Alternative healing or quackery? You may have heard the term “antioxidant” as a buzzword that applies to some vitamins. Antioxidants combat free radicals — molecules produced when your body breaks down food, or by environmental exposures like tobacco smoke and radiation, according to the National Institutes of Health .
