Abstract Vitamin C in beverages such as natural and manufactured fruit and vegetable flavored drinks is stabilized by addition of controlled quantities of cysteine without adverse effects on taste. More especially, beverages containing both Vitamin C and metabolically available iron are stabilized by addition of cysteine, all in specific ratios.
