Innovation is in our DNA

Our founder Dr. Barrie Tan, first and foremost a scientist with a Ph. D. in Chemistry/ Biochemistry, was formerly an assistant professor at the University of Massachusetts in Amherst (Chemistry, Food Science & Nutrition). His mission at American River Nutrition is to deliver the highest quality nutritional products based on sound scientific research. Today, his research focuses on lipid-soluble nutrients that have the potential to slow chronic conditions.

For the last 35 years, Barrie has immersed himself in the world of Vitamin E and is considered one of the world’s foremost experts, credited with commercializing tocotrienol in 3 major natural sources – palm, rice and annatto. His first discoveries were in palm & rice, but due to their high levels of tocopherol, they also lacked potency. Barrie continued his research and was soon rewarded when he found the best-in-class tocotrienol in the annatto plant!

Barrie’s relationship with annatto has spanned 20 years and multiple clinical trials across chronic diseases.

“Discovering the health benefits of annatto was serendipitous, the mission to use American River Nutrition as a vehicle for good is no accident!”
