ASCORBYL PALMITATE is a fat (lipid) soluble VITAMIN C, which means it is more stable and won't flush out of your system like water soluble VITAMIN C (Ascorbic Acid) supplements. Because of its solubility in fats, ASCORBYL PALMITATE may be more effective as an antioxidant in preventing lipid peroxidation than water soluble VITAMIN C. You may require less of a dosage, because it is not being wasted. ASCORBYL is the VITAMIN C component.
