When vitamin E uses its antioxidant function in neutralizing free radicals it also loses this antioxidant function. Vitamin C can change this status; it can regenerate vitamin E back to its native form and is thought to spare glutathione in the body as well. Importantly when ascorbate donates an electron and becomes itself oxidized or consumed the ascorbate radical is relatively harmless. In a double-blind placebo-controlled study in which blood GSH was measured in healthy subjects at several stages?? 500 mg of vitamin C taken daily for 2 weeks significantly raised erythrocyte (red blood cell) glutathione levels. The researchers concluded that vitamin C supplementation at that level can benefit the overall antioxidant capacity of the blood. In another study of similar design?? 1000 mg of vitamin C taken daily for 4 weeks bolstered vitamin E and glutathione content in erythrocyte cell membranes?? compared
