The Science Behind USANA

Science Behind USANA

USANA has a team of in-house experts and scientists dedicated to incorporating knowledge from the latest scientific finding and clinical studies into our products. To stay on the cutting edge, they also partner with renowned research institutions and nutritional experts and consult with our Scientific Advisory Council–a group of independent healthcare professionals dedicated to ensuring we create the best products possible.

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


USANA and High-Quality Manufacturing

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.

Each dietary supplement produced by USANA carries a Potency Guarantee, which ensures that what is stated on the label is actually contained in the product.


A Commitment to Strict Manufacturing Standards

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."

It is USANA's mission to develop and provide the highest-quality, science-based products. By rigorously testing each product for potency and purity and by following pharmaceutical GMP, USANA sets the standard for excellence in dietary supplement manufacturing. Once again, this is proof that USANA products are truly Nutritionals You Can Trust.
