Are supplements worthless? Part 1

Are vitamin and mineral supplements worthless? Are antioxidants dangerous? We turn to Dr. Balz Frei, Professor of Biochemistry & Biophysics, Director of the Linus Pauling Institute at Oregon State University for answers. Was Linus Pauling wrong about taking vitamin C at high doses to “bowel tolerance”?How much vitamin C can the body absorb at a time? Could intravenous vitamin C prove helpful for cancer? Is there a problem with the research methods we currently rely upon to evaluate the efficacy of vitamins and supplements? Should cancer patients getting chemo or radiation stop taking their vitamins?
