USANA’s Scientific Experts


USANA’s world-class scientists review the latest scientific literature and clinical studies on important nutrients, vitamins, minerals, and phytochemicals. They also test the potency and purity of every USANA product to ensure complete and balanced formulas. USANA scientists come from varying fields of expertise, and most have published numerous papers in their careers.

John Cuomo, Ph.D.
Executive Director of Product Development and Technology
Dr. John Cuomo’s experience in synthetic organic chemistry, manufacturing, and analytical methods make his contribution to USANA invaluable. He holds over 20 United States and European patents and is the author of numerous scientific papers. "There are several areas that I think set USANA apart from other nutritional companies," Dr. Cuomo says. "The first is USANA's quality assurance in product development and manufacturing. Few companies have the level of quality control that USANA does. We spend a tremendous amount of time and money making sure that product composition exactly matches what's on the label. One of the ways we do that is through our in-house testing of ingredient potency."

Dr. Cuomo has seen many other companies include product lines solely based on the marketability of the products. "We won't jump on the bandwagon to join the latest health craze simply to make a profit."


Mark Brown, Ph.D.
Director of Product Development

Dr. Mark Brown has completed extensive research in bioorganic chemistry and holds a Ph.D. in organic chemistry from the University of California and a bachelor’s degree in chemistry from California State University, Chico. With more than 15 years of chemistry experience, he is a valuable member of USANA’s scientific team.

 


Brian Dixon, Ph.D.
Executive Director of Health and Science Education

Dr. Brian Dixon joined USANA’s department of research and development in January of 2009. As an integral member of USANA’s scientific staff, Dr. Dixon’s main role was to facilitate and manage all human clinical studies conducted at, and funded by, USANA. In November of 2014, Dr. Dixon was asked to head up the newly formed department of health and science education as its executive director, where he continues to lecture internationally on the importance of nutrition for optimal health.
 
Dr. Dixon earned his PhD in molecular and cellular biology from Oregon State University, where he focused his research on the underlying biochemical mechanisms of the aging process and the therapeutic potential of R-alpha lipoic acid.

Rachel A. Brewer, Ph.D.
Dr. Rachel A. Brewer is a laboratory-trained scientist with a background in molecular biology and nutrition. Growing up surrounded by nature in small-town Alaska, she developed an interest in health and nutrition that guided her career. She completed her undergraduate studies in biological sciences, with a focus on molecular biology, at the University of Alaska Anchorage. During that time, she interned at the Medizinische Hochschule Hannover in Hannover, Germany, researching bacterial contributions to inflammatory bowel diseases.
 
Doctoral studies took Dr. Brewer to the University of Alabama at Birmingham, home of the world-renowned Nutrition Obesity Research Center, where she investigated diet and nutritional impacts on aging and longevity, with a goal of understanding nutritional interventions to help people live healthier, longer lives. Her prior research also explored the role of the molecular circadian clock, in order to understand how time of day at the cellular level can impact health and disease.
 
Dr. Brewer has presented her research at both national and international scientific conferences and has won awards for her scientific endeavors from multiple organizations, including the American Society for Nutrition and the Society for Heart and Vascular Metabolism. Previously, she headed-up the quality control department for a water testing laboratory, ensuring that public water systems remained in compliance with safe water standards. Her interest in improving health through her research experience and expertise in the microbiome has currently led her to continue her work at USANA Health Sciences.
