USANA Expects Second Quarter Sales and Earnings to Exceed Earlier Forecast


SALT LAKE CITY, June 24, 2003--USANA Health Sciences, Inc. (NASDAQ: USNA)
announced today that, based upon preliminary estimates, it currently expects
sales and earnings per share for the second quarter ending June 28, 2003 to
exceed the Company's earlier guidance.

The Company now expects that second quarter sales will approach $47 million and
earnings per share will be in the range of $0.38 to $0.40. Initial guidance for
the second quarter was for sales to approximate $42 million and earnings per
share to be in the range of $0.34 to $0.36.

Gilbert A. Fuller, Chief Financial Officer, said, "Strong top-line growth of
about 47 percent year-over-year is driving the increased earnings. We estimate
that earnings per share for the quarter will be up as much as 150 percent
year-over-year and up about 18 percent compared to the first quarter of 2003.
Sales continue to grow in each of our markets, with this quarter representing
the fourth consecutive quarter of record sales."

USANA plans to announce its second quarter earnings along with new guidance
for the third quarter and for the year on July 15, 2003; executives will hold a
conference call with investors on July 16, 2003, to provide an update.
