John Cuomo, Ph.D.
Executive Director of Research and Development
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."
