Esterified Vitamin CNOW Ascorbyl Palmitate is a highly stable form of Ascorbic Acid, or Vitamin C. Ascorbyl Palmitate is soluble in both water and lipid, and this dual solubility allows it to be incorporated into cell membranes where it helps to protect them from oxidative damage. While it possesses all of the antioxidant properties of Vitamin C, it can also more easily penetrate the blood-brain barrier, facilitating the extension of its antioxidant protection to the brain and nervous system.
