                       USANA Reports Record Sales and EPS
                        Company Raises Guidance for 2003


SALT LAKE CITY, April 15, 2003--USANA Health Sciences, Inc. (Nasdaq: USNA) today
announced definitive results for the first quarter of 2003, reflecting the third
consecutive record for quarterly sales and second consecutive record for
quarterly earnings per share.

For the first quarter of 2003, USANA reported sales of $40.9 million,
representing a year-over-year increase of 42.8% from the $28.6 million in sales
reported in the first quarter of 2002. The growth in sales is due in large part
to the increasing number of active customers and an approximately $1.4 million
benefit from stronger foreign currencies compared to the first quarter of 2002.
Net earnings increased 220.1% to $3.6 million in the first quarter of 2003 from
$1.1 million in the first quarter of 2002. Earnings per share increased 183.3%
to $0.34 per share in the first quarter of 2003 compared to $0.12 per share in
the prior year's first quarter.

Commenting on the results, Dave Wentz, USANA's President, said, "We are proud of
the results achieved in the first quarter. We've now delivered five consecutive
quarters that more than double the prior year's quarterly earnings per share.

"The excitement and enthusiasm of our Associates continues to grow," continued
Mr. Wentz. "We are particularly pleased with the increasing sales and Associate
base in our largest market, North America. International expansion, combined



with improved operating efficiencies is helping drive growth in revenue and
earnings. We should see incremental growth with the opening of operations in
South Korea later this year and in Mexico next year."

Gilbert A. Fuller, Chief Financial Officer, noted, "During the first quarter we
were able to significantly strengthen our balance sheet by eliminating all of
our bank debt. We continue to benefit from a growing Associate base that is
dedicated both to our products and the USANA home-based business opportunity.
Based on the first quarter's operating results, we have increased our guidance
for fiscal year 2003. We now expect annual revenue of approximately $170 million
and earnings per share of approximately $1.40. The results for the latter half
of the year are, of course, dependent upon the success of our opening in South
Korea, scheduled for the third quarter. Looking ahead to the second quarter, we
expect to report revenue of approximately $42 million with earnings per share of
$0.34 to $0.36, depending upon the level of spending associated with the opening
of the Korean market."

review key line items on the statement of earnings with investors on April 16,
2003 at 9:00 AM EDT. Investors may listen to the call by accessing USANA's
