NOW Foods Ascorbyl Palmitate 500 mg provides vitamin C in its fat-soluble ester form — a unique and complementary form of vitamin C that dissolves in lipids rather than water, allowing it to protect cell membranes and LDL cholesterol from oxidative damage in a way that water-soluble ascorbic acid cannot. While standard vitamin C protects aqueous cellular environments, ascorbyl palmitate extends antioxidant protection into fatty tissues including cell membranes, lipoprotein particles, and fatty tissue — making the two forms synergistic when taken together. Ascorbyl palmitate also has a longer biological half-life than ascorbic acid. NOW Foods delivers 500 mg per capsule manufactured in their GMP-certified facility. A specialty vitamin C supplement for those seeking comprehensive, multi-environment antioxidant protection beyond what standard ascorbic acid provides.
