USANA Receives Certification Through NSF's Certified for Sport Program

SALT LAKE CITY--(Business Wire)--
USANA Health Sciences, Inc. (NASDAQ: USNA) recently received
certification of six of its products through NSF International's
Certified for Sport(TM) program. NSF's independent certification helps
athletes make educated decisions about the safety of the dietary
supplements they choose to take.

USANA's Essentials(TM) (Mega Antioxidant and Chelated Mineral),
Proflavonal(R) 90, Procosa(R) II, Active Calcium(TM) and Body Rox(TM)
supplements are now approved to carry NSF's trusted Certified for
Sport mark. USANA also received Good Manufacturing Practices
registration and dietary supplement certification in 2007 through NSF.
These are just some of the third-party findings that help consumers
and athletes know USANA products are Nutritionals You Can Trust.

"The Certified for Sport program validates USANA's guarantee that
our nutritional products are complete, balanced, safe and effective,"
said Dr. Tim Wood, USANA Executive Vice President of Research and
Development. "This latest certification, as with all of our
third-party testing, is based on regular product formulas--the same
products that USANA customers take every day. Receiving this
certification is just another step toward fulfilling our goal of
providing supplements that everyday consumers and world-class athletes
can trust."

The NSF Certified for Sport program was developed to meet the
growing demand of athletes, coaches and all others concerned about
banned substances. The NSF Certified for Sport(TM) Mark helps
consumers know that products have met NSF's stringent independent
certification guidelines. Products are tested and facilities are
inspected for a wide range of substances prohibited by the World
Anti-Doping Agency, the NFL/NFLPA and MLB/MLBPA. The list includes
stimulants, narcotics, steroids, diuretics, beta-2 agonists, beta
blockers, masking agents and other banned substances.

High-quality formulas, a rigorous quality assurance program and
third-party certifications have helped USANA earn the trust of many
world-class athletes and athletic organizations, including United
States Speedskating, Speed Skating Canada, USA Luge and the Sony
Ericsson WTA Tour. "It is imperative for our athletes to know
precisely what they're putting into their bodies," said Stacey
Allaster, President of the Sony Ericsson WTA Tour. "With USANA's
guaranteed assurance of the quality of their products, our athletes
can trust that they will be able to attain optimal health and fitness
without the fear of violating the strict WADA code they all adhere
to."

USANA has taken its assurances to athletes one step further
through its unique Athlete Guarantee Program. Select athletes who
participate in the program are guaranteed compensation up to $1
million if they should test positive for a substance banned by WADA as
a result of taking USANA(R) nutritional products.
