USANA’s BiOmega™ Fish Oil Supplement Approved By ConsumerLab.com

SALT LAKE CITY—(BUSINESS WIRE)—June 17, 2008—USANA Health Sciences, Inc. (NASDAQ: USNA), today announced that its BiOmega™ fish oil supplement was evaluated and approved by ConsumerLab.com, LLC. A leading provider of independent product test results and information, ConsumerLab.com helps consumers and healthcare professionals evaluate health and wellness products.

ConsumerLab.com reviewed BiOmega as part of a larger evaluation of dietary supplements sold in the United States that claim to contain omega-3 fatty acids (EPA and DHA). Products were tested for their omega-3 levels; mercury, lead and PCB contamination; and signs of decomposition. BiOmega received an approved rating in all three testing categories. The review can be found on the company’s Web site at www.consumerlab.com.

ConsumberLab.com stated in its product review that the quality of fish oil and other omega-3 supplements is an important issue because supplement levels vary depending on the source and method of processing. Fish also can have accumulated toxins that could potentially contaminate a supplement. USANA uses a double molecular distillation process to manufacture its BiOmega supplement, ensuring the highest possible purity from mercury, PCBs, pesticides and other heavy metals.

“We are happy to see the results from the ConsumerLab.com trial, but we are not surprised,” said Dr. Tim Wood, USANA executive vice president of research and development. “These results confirm our extensive in-house testing. USANA is committed to only the highest quality manufacturing and analytical testing systems and practices. We are very pleased to receive independent confirmation of the quality and purity of BiOmega from this test.”
