Fat-soluble vitamins, such as vitamin A and D, can be quite toxic at high doses, but vitamin C is reasonably safe as it is easily excreted, Peter McCaffery, Professor of Biochemistry at the University of Aberdeen in the U.K., told. It is also known that intravenous vitamin C is relatively safe when applied under clinical supervision, McCaffery added.
