DeltaGold , developed by American River Nutrition, Inc., is the only tocopherol-free source of tocotrienol vitamin e, and contains the highest amount of delta- and gamma-tocotrienols that is commercially available.Derived from the annatto plant, DeltaGold is all-natural and manufactured in the USA under a patent-protected process vitamin e supplement. American River Nutrition, Inc. started in 1998 in Hadley, Massachusetts. The company was formed in response to the market need for innovative products that are natural, have little to no known side effects, and positively affect the outcome and loss of quality of life associated with age-related and/or degenerative disease states. American River Nutrition, Inc. wholesales DeltaGOLD vitamin E tocotrienol supplement in finished softgels, oil, and powder in bulk. The company was founded by Dr. Barrie Tan. Dr. Barrie Tan earned his doctorate in chemistry with emphasis on biochemistry at the University of Otago, New Zealand. He later became a professor of chemistry and food science/nutrition at the University of Massachusetts, Amherst. His research expertise includes lipid-soluble materials such as carotenoids, tocotrienols/tocopherols, CoQ10, omega-3s and cholesterol. He was the first to introduce tocotrienols benefits to the nutrition industry. He founded American River Nutrition Inc. in 1998 and developed the first-ever tocopherol-free tocotrienol product derived from annatto beans. Today, the focus of his research is on lipid-soluble nutrients that have an impact on chronic and degenerative conditions. Dr. Tan is the senior editor of a compilation with broad focus on tocotrienol, Tocotrienols: Vitamin E Beyond Tocopherols (AOCS & CRC Press), and was the organizer of the 2nd International Tocotrienol Symposium in conjunction with the 103rd Annual Meeting of the American Oil Chemists Society (Long Beach, CA; April 29, 2012).
