Nancy Wick Nereson
As a graduate of the Institute for Integrative Nutrition with certification from the American Association of Drugless Practitioners, I know the value of quality nutritional supplements. It wasn't always that way. Before I was introduced to USANA by a respected wellness pioneer, I had been putting up with some aches and pains that seemed to be part of getting older. After a few months on the nutritional products I felt better than I had in years. Surprisingly, it was even easier to exercise. Since I'm taking the same products that many Olympic and elite athletes trust and use it shouldn't have been such a big surprise. This is the difference optimal nutrition makes.
The easiest way to get started is to take the True Health Assessment on this page. Let me know if you have questions. I'm here to help. It may have been an ordinary day when I found these products. Thanks to them it is now an extraordinary future. For that I am most grateful. My wish for your future is the same. With warm regards, Nancy

We seek out the finest raw materials available, we maintain the strictest quality standards in the industry, and we have an unshakeable commitment to manufacturing integrity. USANA engages in the following third-party testing so that you feel comfortable and confident when choosing USANA every day for life.



Broadly publicized allegations of contaminants in supplements lead many top athletes to wonder if taking supplements will jeopardize their future ability to qualify for competition. To date, no nutritional supplement company has stepped forward to assume their portion of the liability that a banned substance contamination would create.



Science is important because you want to be sure your products are based in research, not trends. USANA has created the following avenues through which it can prove & practice its commitment to nutritional research and development.



Because poor manufacturing can destroy great science, USANA is one of the few companies to manufacture most of its products in its own FDA-registered state-of-the-art facility. Each dietary supplement produced by USANA carries a Potency Guarantee, which ensures that what is stated on the label is actually contained in the product.



At USANA, we customize nutrition and personalize customer care. We don’t look at women ages 25 to 40 or men over 50. We feel each person is their own demographic.


USANA Health Sciences is known for manufacturing the highest quality products backed by a potency guarantee. To ensure you and your family are receiving genuine world-class USANA products, purchase them only through your independent USANA Associate or www.usana.com.
