What’s in Your Supplements: Third-Party Verification


ChecklistUSANA doesn’t settle for anything less than the best. Our supplements are held to the highest possible quality standards at every step in the manufacturing process. Our research and development team is always improving our products to make sure we stay on the cutting edge.

But we can tell you all day long how great USANA is—and it would be true—but it wouldn’t mean much without third-party verification. Luckily, loads of well-respected institutions have tested our standards, facilities, and our products, and found us more than satisfactory.

Third-Party Verification

USANA obtains third-party verification through ConsumerLab.com®. USANA products currently approved through ConsumerLab.com include: USANA® Essentials™, Visionex®, USANA® Probiotic, CoQuinone® 30, Procosa®, and BiOmega™.

USANA’s manufacturing facility is GMP certified by NSF International—an independent, nonprofit organization that certifies products to help protect consumers.

ConsumerLab.comNSF has certified USANA to be in compliance with Good Manufacturing Practices (GMP) for dietary supplements. NSF International is an independent, not-for-profit organization that helps protect public health by writing standards for food, water, air, and consumer goods; testing and certifying products based on those standards, inspecting for GMP, and providing ongoing monitoring.

USANA products also use trusted U.S. Pharmacopeial (USP) testing methods to help ensure they adhere to USANA’s standards for how tablets will break down in the body (disintegration) and also ensure that you get the amounts listed on the label (potency).

USANA’s manufacturing facilities have always been of the highest quality, but in 2011, we made it official: USANA became an FDA-registered facility. This means that not only are all of our products produced with the highest standards, we are also authorized to manufacture over-the-counter (OTC) products.

And if you compare USANA to the competition, you won’t be disappointed. The NutriSearch Comparative Guide to Nutritional Supplements compares hundreds of supplements to determine the highest quality, and USANA has earned the Editors’ Choice Award and 5-Star, Gold Medal rating for the USANA Essentials and HealthPak™.



Athletes-XLIf that wasn’t enough evidence for you, consider this: 700+ world-class athletes—including the Women’s Tennis Association (WTA) and the U.S. Ski and Snowboarding Association (USSA)—trust USANA’s products. Because they know what’s listed on the label is actually what’s in the bottle.

What is the USANA Potency Guarantee?
