Nature source d-alpha tocopherol oil, or RRR-d-alpha tocohperyl, is a natural source form of Vitamin E obtained from vacuum steam distillation of edible vegetable oil products. It is widely used as a source of Vitamin E in food and dietary supplement applications, such as soft-gel encapsulation.

Nature source d-alpha tocopherol is different from synthetic Vitamin E.  Since synthetic Vitamin E is produced by chemical reactions from petrochemicals, it contains additional reaction products (stereoisomers) not normally found in nature. For this reason, natural source Vitamin E contains two times the Vitamin E activity of synthetic Vitamin E on a weight basis.

Natural source d-alpha tocopherol oil is a clear, viscous, amber oil with a mild vegetable oil-like odor. Prolonged exposure to oxygen, light, and/or certain chemicals may result in a gradual darkening. As such it is recommended that normal storage practices for vegetable oils be followed. These should include minimizing contact with air through the use of nitrogen blanketing, avoiding direct sunlight or elevated storage temperatures, and avoiding unnecessary contact with transition metals or alkaline substances.

Natural source d-alpha tocopherol oil conforms to FCC requirements, is produced under certified ISO 9001, 14001 and 22000 programs, and is certified Kosher and Halal. Soybean or sunflower oil may be added to standardize concentration. Non-GM products are available on request.
