Founded in 1992 by microbiologist and immunologist Dr. Myron Wentz, USANA Health Sciences is a science-based company that develops scientifically advanced nutritional, personal-care, and weight management products. The name "USANA" derives from Greek and Latin and means "true health."

USANA was founded with a mission to manufacture the highest quality products without compromise, products that 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. When raw ingredients first arrive at USANA, they are immediately quarantined until they are tested for purity, potency, and quality. If an ingredient fails to meet set standards, it is rejected and returned to the supplier.
