              USANA Announces Record Results for the Second Quarter



SALT LAKE CITY, July 15, 2003--USANA Health Sciences,  Inc. (Nasdaq: USNA) today
announced financial results for the second quarter ending June 28, 2003.

Sales for the second quarter of 2003 totaled $47.2 million, an increase of 47%
compared to $32.1 million reported in the second quarter of 2002. The growth in
sales is primarily due to the increasing number of active customers and a
positive impact from stronger foreign currencies of about $2.3 million compared
to the second quarter of 2002. Net earnings of $4.3 million were generated in
the second quarter, compared to $1.7 million in the prior year's second quarter.
Earnings per share for the quarter were $0.41 per share, an increase of $0.25
per share or 156% over the second quarter of 2002.

"We continue to reach record levels for both sales and earnings," commented Dave
Wentz, President of USANA. "The worldwide growth in active Associates remains a
key driver of our success. It is gratifying to see more and more people around
the world benefiting from both the health benefits and home-based business
opportunity USANA provides. In July we officially opened our business operations
in South Korea. We anticipate that Korea will become a significant market for us
and are pleased with the high level of excitement we have seen from our
Associate leaders."

"Sales continue to surpass our expectations," stated Gilbert A. Fuller, Chief
Financial Officer of USANA. "Even without the $2.3 million benefit from stronger
foreign currencies relative to the US dollar, our year-over-year sales growth
was a remarkable 40%. Based on the better than expected sales, we have increased
our guidance for the remainder of 2003. We now anticipate annual sales to exceed
$190 million with earnings per share approaching $1.65. As we move into the
third quarter we expect sales to approach $52 million with earnings per share in
the range of $0.43 to $0.45. We expect Korea to be a significant market, but
realize that our upward guidance is dependent in part upon the actual results of
that market."

USANA executives will hold a conference call to discuss this announcement and
review key line items on the statement of earnings with investors on July 16,
2003 at 9:00 AM EDT. Investors may listen to the call by accessing USANA's
