By the summer of 1994 the company had begun its own publication for its distributors, USANA Magazine, in which Wentz announced that he had sold his controlling interest in Gull Laboratories to Fresenius, a German health care firm with annual sales of over $1 billion.

In 1995 United States sales reached $21.5 million, and Canadian sales accounted for an additional $3 million.

By early 1996 USANA had joined the Direct Selling Association (DSA), a trade group for firms in network marketing and other kinds of direct sales.

According to the firm's 1997 annual report, USANA received about 82 percent of its sales from nutritional products.
