Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C, it is also used as an antioxidant food additive (E number E304). It is approved for use as a food additive in the EU, the U.S., Australia, and New Zealand.
Ascorbyl palmitate is known to be broken down (through the digestive process) into ascorbic acid and palmitic acid (a saturated fatty acid) before being absorbed into the bloodstream. Ascorbyl palmitate is also marketed as "vitamin C ester".
Ascorbyl palmitate is a highly bioavailable, fat-soluble derivative of ascorbic acid. It possesses all the benefits of vitamin C, but, unlike the water-soluble form, is able to be stored in the lipid cell membrane until the body is ready to put it to use. Vitamin C offers a wide range of support for the human body. It is a potent antioxidant and free radical scavenger. It supports the body by enhancing defense system cell activity. It is essential for the formation and maintenance of intercellular ground substance and collagen. Vitamin C aids in the absorption of iron and the formation of red blood cells and converts folic acid to active folinic acid. It maintains healthy histamine release and supports lymphocyte formation. Vitamin C is also required for the synthesis of carnitine and steroids.
Ascorbyl palmitate is actually a variant of ascorbic acid, commonly known as vitamin C. This fat-soluble supplement provides antioxidant protection that helps to improve overall health. Sometimes referred to as ester, this form of ascorbic acid usually comes as an antioxidant pill or food additive. Dosage amounts vary depending on the product and the health needs of the person. This substances produces no known side effects, but people with specific conditions should seek the advice of a doctor before taking the supplement.
