Myron W. Wentz Net Worth

Myron W. Wentz has an estimated net worth of $1.1 billion, according to Forbes Real-Time Billionaires, Myron W. Wentz profile (figures as of October 20, 2026). That is down from a peak of $1.7 billion.

Myron W. Wentz is a businessman and microbiologist best known for founding USANA Health Sciences. The company sells nutritional supplements and skincare products through multilevel marketing. Before that, he built Gull Laboratories, a diagnostics company he started in 1974. He developed a test for diagnosing Epstein-Barr virus infection there. He later founded Sanoviv Medical Institute in 1998, a holistic care center near Rosarito, Mexico.

His wealth came mainly from building and keeping a large stake in USANA. Forbes says he owns 40% of the company, which has $850 million in net sales and trades on the NYSE. He took USANA public in 1996. Earlier in his career, he sold his stake in Gull Laboratories in 1994 for $22 million. Forbes currently values his fortune at $1.1 billion on its real-time billionaires tracker as of October 20, 2026.

How Myron W. Wentz built his fortune

Wentz first made his mark in diagnostics. In 1974, he launched Gull Laboratories as a one-man business focused on tests for hospitals and labs. One of its products was a test for diagnosing Epstein-Barr virus infection. He sold his stake in 1994 for $22 million, giving him capital from a company he had grown in the medical testing field.

His biggest source of wealth became USANA Health Sciences, which he founded in 1992. The company sells nutritional products, dietary supplements, and skincare items. He took it public in 1996, and Forbes says he still owns 40% of the business. That stake matters because USANA is a public company with $850 million in net sales. He retired as USANA's chairman in December 2019, but his ownership remains central to his fortune.

Forbes net worth history

Forbes has tracked Wentz's fortune at several points, with the estimate moving over time. On the World's Billionaires List, Forbes put him at $1.7 billion in 2019. By the 2026 annual list, the estimate was $1.2 billion. Those shifts line up with the value of his large USANA stake, since Forbes ties his wealth to health products and his holdings in the public company.

The latest reading is lower still. Forbes shows Wentz at $1.1 billion on its real-time billionaires tracker as of October 20, 2026. He is listed as self-made by Forbes. Outside USANA, his career also includes Sanoviv Medical Institute, which he founded in 1998. But the clearest money engine in the public record is his long-held ownership in USANA after taking the company public in 1996.
