Kelly Dean Harvey entered his plea Tuesday in U.S. District Court in Salt Lake City. He is charged with conspiracy, mail and wire fraud and money laundering.
A 31-count indictment says Harvey collected more than $2 million for erectile dysfunction products marketed as "100 percent natural."
The Food and Drug Administration began warning consumers in 2009 that the products had raw ingredients from China that could cause health problems.
Harvey's attorney, Jamie Zenger, has denied the products were harmful and says his client cooperated with the FDA.
