USANA (NYSE: USNA) creates premium nutritional products built on one simple idea: if you feed the cells in your body exactly what they need, your health will benefit. This concept fuels our endless drive to innovate and
advance the science of nutrition—putting a healthy, happy life within reach for all.

Our Founder

USANA was founded in 1992 by Dr. Myron Wentz, an internationally recognized microbiologist and immunologist. Propelled by the premature and preventable death of his father in 1957, Dr. Wentz has spent his entire adult life seeking to create the most advanced dietary supplements science can produce. Prior to USANA, Dr. Wentz founded Gull Laboratories in 1974 and is well known for creating the first commercially available diagnostic test for the Epstein-Barr virus.

Quality Standards

USANA’s manufacturing facilities operate at pharmaceutical-level Good Manufacturing Practices (GMP)—above and beyond what is required by law for dietary supplements. We rigorously test our products and strictly adhere to procedures and documentation not followed by other supplement companies. We also create, test, produce, and store the majority of our products at our state-of-the-art facility in Salt Lake City, Utah.

International Business

USANA operates in 24 diverse markets around the world, meaning you can influence people all over the globe as you grow your own international business.
