Vitamin C Palmitate/Ascorbyl Palmitate is a fat-soluble form of ascorbic acid, or vitamin C. Unlike ascorbic acid, which is water-soluble, ascorbyl palmitate is not water-soluable. Consequently ascorbyl palminate can be stored in cell membranes until it is required by the body. Many people think vitamin C (ascorbyl palminate) is only used for immune support, but it has many other important functions. A major role of vitamin C is in manufacturing collagen, a protein that forms the basis of connective tissue - the most abundant tissue in the body. Ascorbyl palmitate is an effective free radical-scavenging antioxidant which promotes skin health and vitality.
