Antares Health Products’ Vitamin E TPGS is a water-soluble solid form of natural-source vitamin E. TPGS or d-alpha-Tocopheryl Polyethylene Glycol Succinate-1000, is a waxy solid that melts at 36 to 41 degrees C. It is water soluble and provides a readily absorbed source of vitamin E especially for individuals who have difficulties absorbing fat-soluble vitamin E that is often caused by diseases and conditions that affect liver bile production and secretion such as Cholestasis, Crohn’s, Cystic Fibrosis and drug therapies. Because TPGS emulsifies with fats, it can be used in conjunction with fat-soluble drugs and nutrients to enhance their bioavailability. It is both hydrophilic andlipophilic to improve bioavailability and is easily incorporated into foods and beverages. As a water-soluble form of vitamin E, TPGS is used as a uniquely productive carrier in dietary supplement formulations.
