CSI Vitamin C Ester Ascorbyl Palmitate is a high-quality, fat-soluble form of vitamin C. Unlike more common, water-soluble vitamin C, which must be continually replaced through diet, ascorbyl palmitate is fat soluble and stored in the body for longer periods of time.   Vitamin C is required for proper development and function of many parts of the body.  Vitamin C supports the development and repair of body tissues. Vitamin C is needed to form the protein collagen, which the body uses to make skin, tendons, ligaments and blood vessels. Because vitamin C is an antioxidant, it can reduce damage that free radicals, chemicals and pollutants cause to the body’s cells.
