About USANA Health Sciences

We were founded by a scientist—not a corporate suit.

USANA’s founder, Dr. Myron Wentz, is an internationally recognized microbiologist, immunologist, and a pioneer in infectious disease diagnosis. In 1974, he founded Gull Laboratories to develop viral diagnostics, and his greatest successes during this time included the first commercially available diagnostic test for Epstein-Barr virus, better known as the virus that causes mononucleosis.

But success was never Myron Wentz’ only aim. Instead, he centered his life around his vision of that he dreams of a world free from pain and suffering. A world free from diseases. Therefore he founded USANA to help further his dream by providing people all over the world with the most advanced supplements science can produce.

This is why USANA is a company based on continuous product innovation. This is why we have a very stringent manufacturing processes, through ongoing scientific research, and an insatiable drive to produce exceptional products.
