Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C, it is also used as an antioxidant food additive (E number E304). Oral supplements of ascorbyl palmitate are less effective, due to the substance breaking down again into its components before being digested^[1]. Ascorbyl palmitate is also marketed as "vitamin C ester.
