Vitamin C is classically seen as a vitamin taken in small doses to prevent scurvy and support the immune system. However, there is increasing evidence show- ing that vitamin C has a much greater role to play in human health, particularly when supra-physiological doses are administered either orally or intravenously for patients with a wide range of conditions, including infections, cancer, car- diovascular diseases, wounds, diabetes and anaemia. Few incidences of severe adverse effects have been reported following vitamin C administration. The role of vitamin C in disease intervention at doses higher than previously considered relevant should be thoroughly investigated in a clinical setting.
