Dr. Barrie Tan, Ph.D., is a renowned expert in vitamin E research, particularly its most potent form, tocotrienols. With a doctorate in Chemistry and Biochemistry from the University of Otago and academic experience at the University of Massachusetts, he discovered tocotrienols in palm, rice, and later annatto—the only known plant source free of tocopherols. He later founded American River Nutrition to commercialize DeltaGold®, a tocopherol-free tocotrienol supplement. Over his 35-year career, Dr. Tan has led numerous clinical studies highlighting the benefits of tocotrienols in reducing inflammation, improving cholesterol and liver health, and supporting healthy aging.
