The Safety of High Doses of Vitamin C

Conference paper

Abstract

For many years, some scientific experts, and some physicians, have advocated taking large doses of vitamin C, which has been thought to be protective against the common cold and other virus infections. Such dosages are considerably in excess of the recommended daily allowance (RDA) for the vitamin. More recently the indisputable properties of vitamin C as an antioxidant and free radical scavenger have been of particular interest as public attention has been focused on the possible association of enhanced intakes of antioxidants with lowered risk of degenerative diseases, notably some forms of cancer and cardiovascular disease. For all these reasons many members of the public take quite large supplements of vitamin C in the belief that this will provide health benefit. There is, however, not as yet substantiated scientific and medical evidence that this practice will result in lowered disease risk or any therapeutic benefit. It is thus essential that the ingestion of large doses of vitamin C does not carry with it any proven detrimental effects which might have the opposite consequence from that which is expected.
