In addition to conducting countless clinical studies in-house, USANA scientists often collaborate with respected universities and research centers to ensure our formulations remain on the cutting-edge of nutritional science and to test the effectiveness of our products in helping consumers achieve optimal health.
USANA has partnered with a number of universities to conduct research studies, including the University of Utah, Boston University, and the University of Sydney. In early 2008, USANA announced the results of a large, third-party clinical study completed at the University of Colorado Denver, which confirmed that lifestyle changes involving diet, supplementation, and exercise, can improve metabolic syndrome (Wyatt HR, et al).
Specific university research sponsored by USANA includes:

Linus Pauling Institute
In 2007, USANA announced a 10-year partnership with the Linus Pauling Institute (LPI). Based at Oregon State University, LPI is one of the nation’s first two Centers of Excellence for Research on Complementary and Alternative Medicine designated by the National Center for Complementary and Alternative Medicine of the National Institutes of Health. The Linus Pauling Institute conducts research based on the idea that a balanced and nutritious diet is the key to optimal health. USANA works closely with LPI to explore new products and ingredients and conduct extensive studies on the health benefits associated with key nutrients.

The Orthopedic Specialty Hospital (TOSH)
USANA and The Orthopedic Specialty Hospital (TOSH) began formal research collaboration in 2009, though an informal research partnership existed since 2007. TOSH is a leading facility for orthopedic surgical care, rehabilitation, physical therapy, sports performance training, and nutrition counseling. In addition, TOSH has an extensive research program that includes orthopedic surgery, sports medicine, exercise physiology, sports biomechanics, physical therapy, occupational therapy, athletic sports performance training, and nutrition. Working in close collaboration with scientists, doctors, therapists and students, TOSH works to develop a better understanding of factors that affect human performance, the risk of injury to sports participants of all ages and levels, and optimal medical interventions to help get individuals back to their healthiest as quickly as possible.

Glycemic Index Foundation
A collaboration between the University of Sydney, the Juvenile Diabetes Research Foundation of Australia, and Diabetes Australia—the Glycemic Index Foundation (GIF) backs the GI Symbol Program in Australia. The GI Symbol Program is the only independent worldwide GI certification program requiring foods meet a number of criteria to prove they are a healthy choice within their food group. All USANA Foods carry the GI Symbol in Australia, and all testing data quality has been verified by the GIF.
