USANA Health Sciences formulates exceptional, science-based nutritional and personal-care products. However, inferior manufacturing can destroy even the greatest product formulations. For this reason, USANA manufactures its own nutritional supplements, and voluntarily meets pharmaceutical Good Manufacturing Practices (GMP). Pharmaceutical GMP standards are far more stringent than the food GMP requirements set by the U.S. government for supplements.


To adhere to the exacting standards of pharmaceutical GMP, and to ensure the quality of every product manufactured, USANA inspects all raw ingredients before they are mixed, tests the product during manufacturing, and performs a final analysis before any product is sent to the customer. USANA's Quality Assurance team keeps track of every detail, from careful testing and evaluation of raw materials, to meticulous product shipping and storage. Visitors to USANA's corporate headquarters can take a self-guided tour to see USANA's manufacturing process firsthand.

Many of USANA's products are approved for use by Olympic athletes.
USANA's team of scientists continually works with in the top nutritional and scientific evidence in the development of their products to help you achieve optimal health through supplementation.
