Gary Williamson, PhD

“There’s no doubt now about the benefits of a plant-based diet, it’s more about the detail: how important are plant nutrients for this particular condition, or how does this botanical work for these chronic conditions of aging?” 

Dr. Williamson focuses his research on how the body absorbs dietary polyphenols, the bioactive molecules found in many plant-based foods, beverages and supplements, and the mechanisms by which they reduce the risk of healthspan-impacting conditions like cardiovascular disease. He has made major advances in understanding plant polyphenol bioavailability and shown that certain polyphenols influence cellular energy metabolism and the appearance of glucose in the blood after a meal – important risk factors for type 2 diabetes.  

He is currently exploring the effects of the energy-regulating molecule AMPK. One area of interest is how AMPK activation, thought to positively affect energy metabolism and other factors that support health, may contribute to healthspan. He is testing the influence of botanical extracts identified by Amway Innovation & Science in targeting AMPK.  

Dr. Williamson also is exploring how certain foods and supplementation may affect satiety, the feeling of fullness and satisfaction we experience after a meal, and its implications for managing obesity. In addition to shared interests in healthy aging and healthy weight, Dr. Williamson has affinity for Amway labs’ level of analytical capabilities and the depth of Amway scientists’ dedication to serious research. 

Dr. Williamson obtained his PhD in Biochemistry at the University of Sheffield in the UK. He has extensive experience in international research in academic, institute and industrial environments. He held a prestigious five-year European Research Council Advanced Grant to study the mechanism of the true chronic effect of dietary polyphenols. A highly cited author, he has presented at more than 200 research seminars at international scientific conferences and research centers.
