Abstract
Abstract Vitamin C is stabilized by the addition of 1 to 6 percent histidine or 0.4 to 3 percent glycine or 0.7 to 4 percent methionine based on the weight of the Vitamin C. The stabilized Vitamin C composition is used to fortify beverages. Metabolically available iron can be included within the stabilized Vitamin C composition.
