Usana Health Sciences, Inc., or USANA, is an American multi-level marketing company based in West Valley City, Utah. As of 2021, Usana was the 14th largest multi-level marketing company in the world by revenue. The company manufactures most of its nutritional products, dietary supplements, and skincare products at a West Valley City facility. Its products are sold in 24 countries via a network of independent distributors. History In 1992, immunologist and microbiologist Myron Wentz moved his diagnostic testing company, Gull Laboratories, from Salt Lake City to West Valley City, Utah, and spun it into Usana Health Services, a multilevel marketing manufacturer of supplements. Beginning in 1993, Dallin A. Larsen served as Usana's vice president of sales (and later as a consultant to Usana's president and special advisor to the board of directors) prior to founding the MLM beverage company Monavie in 2005. Usana's products are not available through retail channels, and can only be obtained through one of its independent distributors (referred to as "associates") or by direct order through the company. On 20 February 2007, Barry Minkow, founder of the Fraud Discovery Institute, distributed a 500-page report to officials at the U.S. Securities and Exchange Commission (SEC), the Federal Bureau of Investigation (FBI), and the Internal Revenue Service (IRS) accusing Usana of operating an illegal pyramid scheme. The SEC conducted an investigation of Usana's business practices in March 2007 and found nothing incriminating, concluding its inquiry with no enforcement action recommended. Minkow acknowledged that he was shorting Usana's shares, hoping to profit from a drop in the stock price. In April 2007, a class action lawsuit was filed that alleged Usana common stock had artificially inflated prices. In August 2007, Usana was notified by the Securities and Exchange Commission (SEC) that its shares were subject to delisting from the NASDAQ due to its Form 10-Q, and was determined to be in compliance that October. In January 2008, a shareholder suit was filed with allegations that Usana had misled investors about the sustainability of its growth and business model. The cases were dismissed and the company was cleared by the U.S. Securities and Exchange Commission after an informal inquiry into the allegations, stating that it did "not intend to recommend any enforcement action by the Commission." Later that year, two Canadian Usana distributors were awarded $7 million in compensation for damages related to their wrongful dismissal from the company. The
