                          USANA Announces Record First
     Quarter Results; Net Sales Up 24 Percent; Net Earnings Up 44 Percent;
                        Earnings Per Share Up 50 Percent


    SALT LAKE CITY--(BUSINESS WIRE)--April 19, 2005--USANA Health
Sciences Inc. (NASDAQ: USNA) today announced record financial results
for the first fiscal quarter of 2005 (ended April 2, 2005). The
company achieved record net sales in the first quarter of $76.6
million, an increase of 24%, compared with $61.8 million in the first
quarter of 2004. This growth was driven by a 24% increase in the
number of active Associates and by increasing sales of the company's
recently reformulated line of skin and personal care products, Sense.
    Earnings from operations in the first quarter of 2005 grew to
$13.6 million, or 18% of net sales, compared with $9.3 million, or 15%
of net sales, in the first quarter of 2004. The company achieved net
earnings in the first quarter of 2005 of $8.9 million, an increase of
44%, compared with net earnings of $6.2 million in the first quarter
of 2004. Earnings per share in the first quarter increased to $0.45
per share, an increase of 50%, compared with $0.30 per share in the
first quarter of 2004.
    "We are pleased to report our 11th consecutive quarter of record
net sales," said Dave Wentz, president of USANA. "We are particularly
pleased with the fact that we achieved double-digit, year-over-year
growth in all but one of our markets. Also, overall, the number of our
active Associates grew to 119,000, an increase of 24%, compared with
our first quarter of last year. The demand for our recently
reformulated Sense products has grown, and our Associates have used
this opportunity to build their businesses through the sale of these
revolutionary, self-preserving products. We expect strong demand for
these products in the future. We have increased our inventory of these
products in each of our markets so that we can begin to market them
more aggressively."
    "Our primary strategy is to increase sales in our existing
markets," continued Wentz. "We also are working to open one new market
before the end of the third quarter of 2005, and we will make an
announcement as the time for that opening approaches."
    Gilbert A. Fuller, USANA's chief financial officer, said, "We are
pleased with our record results for the first quarter. Our operating
margin improved significantly, both sequentially and compared with the
first quarter of last year in which, notably, our earnings were
reduced by the costs of our entry into Mexico. We continue to improve
our operating efficiencies, especially in the manufacture of our Sense
products at our Wasatch facility. Our inventories in the first quarter
increased by approximately $5 million, which was primarily a result of
the build-up in our Sense products."
    "With respect to guidance," Fuller continued, "we expect net sales
in the second quarter of 2005 to be $78 million to $80 million, an
increase of as much as 19%, compared with $67.2 million in the second
quarter of last year. We also expect earnings per share in the second
quarter of 2005 to be $0.46 to $0.47, an increase of as much as 31%,
compared with $0.36 in the second quarter of last year. We remain
optimistic about the prospects for the full year 2005. We reiterate
our previous guidance for 2005 net sales to be between $319 and $327
million, representing 17% to 20% growth compared with 2004. Also,
given our improving margin trend, we are raising our guidance for
earnings per share for 2005 to be $1.85 to $1.90."
    USANA will hold a conference call and webcast to discuss this
announcement with investors on Wednesday, April 20, 2005 at 11 a.m.
EST. Investors may listen to the call by accessing USANA's Web site at
