For Immediate Release

           USANA Announces 2.65 Million Share Repurchase from Founder

SEPTEMBER 21, 1999--USANA, Inc. today announced the completion of a 2.65-million
share  repurchase  from its founder,  Myron W. Wentz,  Ph.D.  Effective July 30,
1999,  the company  agreed to repurchase  2,650,000  shares of USANA stock owned
beneficially  by Dr.  Wentz,  USANA  CEO and  Chairman,  at a price of $7.90 per
share.  This  purchase  reduces Dr.  Wentz'  holdings from 57.1% to 45.9% of the
issued  and  outstanding  shares  of  the  company.   In  connection  with  this
transaction,  the company  borrowed  approximately  $18  million,  through a new
credit  agreement  with the Bank of America,  which  includes a $10 million term
loan and a $15 million revolving line of credit.

     "These transactions reflect USANA's financial strength," commented Gilbert
A.  Fuller,  Chief  Financial  Officer.  "Bank of America was pleased to provide
funding for the stock  buyback,  demonstrating  their  confidence  in our strong
business prospects."

     "By repurchasing shares from Dr. Wentz at a price that reflects the stock's
relatively low valuation,  we are able to achieve immediate prospective earnings
per share benefits,"  continued Mr. Fuller. "The reduction in shares outstanding
significantly  outweighs the interest cost on the new debt,  thereby  benefiting
all of our shareholders."

     Separately today,  USANA announced a restructuring of its operations in its
European operations  together with other cost savings,  primarily to be achieved
through the implementation of a new customer service software system.
