"I want you to be aware of the very serious commitment we have to research and development.

Athlete Guarantee Program

Taking nutritional supplements to help maintain health shouldn't place an athlete at risk for testing positive for a banned substance. To date, no nutritional supplement company has stepped forward to assume their portion of the liability that a banned substance contamination would create. USANA offers an ironclad solution through its Athlete Guarantee Program. This confident stance in a high stakes venture strengthens our industry-leading position and affirms our commitment to providing "Nutritionals You Can Trust."
