In a new book, scientists at the University of California, Berkeley, claim their belief that daily intakes of antioxidant vitamin supplements, both Vitamin C and Vitamin E, "help inactivate free radicals," which are unstable molecules in the body that can damage cells and lead to chronic diseases. "The Complete Home Wellness Handbook" was written by Dr. John Edward Swartzberg, Dr. Sheldon Margen, and the editors of the UC Berkeley Wellness Letter. "There have been many studies on C and E, and scientists are only beginning to understand how these and other antioxidants work. The evidence is accumulating bit by bit," the editors said. According to the authors, it is difficult to get the recommended amount of Vitamin E from food, and most foods considered good sources of Vitamin E are high in fat. Numerous studies have demonstrated that natural Vitamin E, made from soybeans, is more effective than the synthetic version of Vitamin E.
