USANA Potency Guarantee

High-Quality Manufacturing

USANA Health Sciences is one of America’s leading companies in the field of health and nutrition. USANA helps improve the lives of thousands of people around the world with their mission of developing and providing the highest quality, science-based health products. Each USANA product comes with a 100 percent potency guarantee. This guarantee ensures what is stated on the label is actually contained in the product.

USANA is committed to nutritional research and development. That’s why they have a group of in-house experts dedicated to the latest scientific findings and clinical studies. USANA is also committed to research partnerships with nutritional experts and consults regularly with their Scientific Advisory Council—a group of independent health-care professionals dedicated to helping USANA create the best products possible. 

At USANA, scientific research is at the heart of every product they offer. Whether in studies conducted by top scientists in their on-site laboratories or findings from the many research partnerships they have across the globe, USANA is fully committed to the research and development of cutting-edge nutritional technology.

Their state-of-the-art manufacturing facilities ensure that each product they create is made with the same high quality that sets them apart from others in the past and will allow them to lead the field in the future.

The Food and Drug Administration requires that dietary supplement manufacturers follow Good Manufacturing Practices (GMP) for dietary supplements (21 CFR, part 111). USANA, however, voluntarily follows the more stringent GMP for pharmaceuticals as the basis for its quality assurance program, which regulates virtually every aspect of manufacturing, including facility design and maintenance, raw material specification and control, supplier validation, product design and testing, and more. This voluntary adherence to GMP for pharmaceuticals means that USANA treats nutritional supplements with the same care that goes into the manufacturing of over-the-counter products.

In addition, USANA has acquired Drug Establishment Registration with the U.S. Food and Drug Administration. This means USANA operates an FDA-registered facility, following the FDA’s highest possible standard for manufacturers. 

Also, where applicable, USANA voluntarily tests its supplements to make sure they meet trusted United States Pharmacopeia (USP) standards and specifications for potency, uniformity, and disintegration. 

In several countries around the world, supplements are more highly regulated than in the United States. In Australia, for example, the Therapeutic Goods Administration (TGA) mandates that manufacturers follow a set of GMP identical to pharmaceutical GMP in the United States. As an Australian supplier, USANA is regularly inspected and audited by the TGA to ensure that their GMP standards are met. 

Aside from meeting the criteria of regular TGA audits, USANA has voluntarily obtained additional third-party verification of GMP status. Since 2006, USANA’s Salt Lake City, Utah, manufacturing facility has been certified to be in compliance with NSF/ANSI Dietary Supplement GMP requirements set forth by NSF International. According to NSF, "GMP registration reflects [a] continued commitment to ensuring quality and satisfaction and gives companies confidence that their organization operates in conformance to established GMP."

USANA® CellSentials™ (Vita-Antioxidant and Core Minerals), Procosa®MagneCal D™, and the HealthPak™ have all been exhaustively tested by NSF International and have been found to contain all ingredients at the labeled amounts. NSF is an independent, not-for-profit organization that helps protect consumers by certifying products and writing standards for food, water, and consumer goods. 

A number of USANA supplements have also been evaluated and approved by ConsumerLab.com, a leading provider of independent test results and information. 

USANA is a member of the United Natural Products Alliance (UNPA)—an association of dietary supplement and functional food companies that share a commitment to provide consumers with natural health products of superior quality, benefit, and reliability.

Research Partnerships
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 

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. 

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.

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.

So many pills. So little time. That’s why we came up with Nutritional Hybrid Technology—our state-of-the-art approach to formula design and manufacturing that allows us to combine two tablets into one. Not only does this open the door to further innovation in supplement design and manufacturing, but it simplifies your life by cutting your daily pill intake in half while still giving you full nutritional value.

Take a Tour of USANA's Home Office
USANA was founded with a mission to manufacture the highest-quality products without compromise—products people can trust. Because poor manufacturing can destroy great science, USANA is one of the few companies to manufacture most of its products in its own state-of-the-art facility. To ensure that the formulas developed in USANA's laboratories are produced consistently, the same process is followed each time manufacturing begins.

The Highest Rated Supplements in the world

In addition, when compared to 1,500 other products, USANA was named Editor’s Choice, and two products (CellSentials and HealthPak) each received a top 5-star rating and Gold Medal of Achievement from NutriSearch Comparative Guide to Nutritional Supplements™, Consumer Edition. 

Team USANA the $1 Million Dollar Athlete Guarantee Program

Team USANA Athletes

USANA Health Sciences, a worldwide leader in science-based nutritional products, is proud of its partnership with over 600+ of the world's most elite athletes. These partnerships form "Team USANA".

Trust is a major issue for athletes competing for a place in the Olympics and other high profile athletic competitions. Taking nutritional supplements to help maintain health shouldn't place an athlete at risk for testing positive for a banned substance. Broadly publicized allegations of contaminants in supplements lead many top athletes to wonder if taking supplements will jeopardize their future ability to qualify for competition. In fact, national Olympic committees have warned athletes of the potential danger of contaminants, encouraging them not to consume any nutritional supplements.

To date, no nutritional supplement company has stepped forward to assume their portion of the liability that a banned substance contamination would create. USANA offers an ironclad solution through its Athlete Guarantee Program. This confident stance in a high stakes venture strengthens our industry-leading position and affirms our commitment to providing "Nutritionals You Can Trust."

Our Athlete Guarantee Program permits select athletes, some of whom have high profiles and are highly compensated, to enter an agreement with USANA which states that, during the term of the agreement, should the athlete test positive for a banned substance included in World Anti-Doping Agency regulations as a result of taking USANA nutritional products, USANA will compensate that athlete two times their current annual earnings up to $1 million, based on the athlete’s personal level of competition, endorsement, and other income, as well as other factors.

USANA has earned NSF Certified for Sport® certification for its nutritional products. USANA meets NSF International Certified for Sport requirements which is an answer for the professional athletes' that desire safe dietary supplements. USANA completed the requirements of the NSF Athletic Banned Substances Certification Program receiving NSF's Certified for Sport.  USANA products have been tested and guranteed free of banned substances under the guidelines of Informed-Choice LLC and by a labratory with ISO 17025 accreditation. USANA offers an ironclad solution through its Athlete Guarantee Program.
