When researching the various nutritional products available on the market for the House of Speed athletes, co-founder Dr Schutt chose USANA. USANA was the only product out of the many products that he researched that stood out for having the highest quality multi-vitamin, mineral and antioxidant products. This is important to the athletes that House of Speed trains because to excel in sports and prevent muscle and connective tissue break down in the body from exercise, athletes need proper nutrition and antioxidant support. USANA provides the highest quality product and is also guaranteed to be free from banned substances. Therefore you can trust USANA to be safe for your athlete and for your family. USANA Health Sciences formulates exceptional, science-based nutritional and personal-care products. However, inferior manufacturing can destroy even the greatest product formulations. For this reason, USANA manufactures its own nutritional supplements, and voluntarily meets pharmaceutical Good Manufacturing Practices (GMP). Pharmaceutical GMP standards are far more stringent than the food GMP requirements set by the U.S. government for supplements.

To adhere to the exacting standards of pharmaceutical GMP, and to ensure the quality of every product manufactured, USANA inspects all raw ingredients before they are mixed, tests the product during manufacturing, and performs a final analysis before any product is sent to the customer. USANA's Quality Assurance team keeps track of every detail, from careful testing and evaluation of raw materials, to meticulous product shipping and storage. Visitors to USANA's corporate headquarters can take a self-guided tour to see USANA's manufacturing process firsthand.
