KAL® Hyaluronic Acid is enteric coated to help the tablet survive the stomach acid and pass into the small intestine where the ingredients are released and absorbed. Also contains Vitamin C as ascorbic acid to assist metabolism of Hyaluronic Acid. The skin contains 50% of the total amount of Hyaluronic Acid found in the body. The body produces its own Hyaluronic Acid, but produces less as the body ages. This can lead to decreased moisture levels in the skin.
