[2009] Vitamins: It's The Dose That Does it "I have been consulted by many researchers who proposed bold studies of the effects of massive doses of ascorbate (vitamin C). Every time the university center, the ethics committee, or the pharmacy committee deny permission for the use of massive doses of ascorbate and render the study almost useless. Seasoned researchers depending upon government grants do not even try to study adequate doses."---Robert F. Cathcart III, M.D
