USANA’s mission is to develop and provide science-based health products of the highest quality, distributed internationally through direct sales. All of Usana’s strategies and decisions are filtered by its core values of Health, Excellence, Integrity, and Community.

Having been with Usana as an independent associate since 2011, we can say 100% that Usana is consistent with its vision, mission, and core values in everything it does.

Now, why should you consider Usana? Hundreds of nutritional supplements claim that they are the best. Usana does not claim that it is the best. It simply wants to be DIFFERENT.

But let’s take a look at the evidences that will show you the true standing of Usana in the world of dietary supplements, not according to Usana, but according to third parties. We believe that matters more. Don’t you think so?  

Why Can You TRUST Usana Nutritional Supplements?

Since Usana started in 1992, Usana has never had any product recall worldwide. That’s a company consistently committed to quality. It has also won over 700 local, national, and international awards.

The following list covers five reasons that stand out as being the most important decision-making factors for many loyal USANA product users worldwide.

  • 1 USANA has a Potency Guarantee – what’s on the label is also on the tablet.

When you trust your health to USANA, you know exactly what you’re getting. This is because your USANA Nutritionals come with a potency guarantee.

To receive the Potency Guarantee seal—featuring the signature of USANA Founder Dr. Myron Wentz—each supplement is tested for the following:


  • Purity—free from impurities or contamination
  • Identity—ingredients in the product are verifiably the ingredients on the label
  • Composition—contains exactly what it is supposed to, in exactly the right amounts
  • Strength—offers the proper concentration of ingredients
  • Quality—meets all specified expectations    
  • 2 Third party testing says it is the highest-rated supplement.

Usana is the highest rated brand among 1,600 supplements tested in the Nutrisearch Comparative Guide to Nutritional Supplements (2017), being the only brand to receive a 5-Star Platinum+ rating.

  • 1 Usana makes over 90% of its products in-house

Welcome to the world of science-based nutritional supplements.

  • 3 Usana's founder is an award-winning scientist, not a businessman.

Dr. Myron Wentz has a PhD in Immunology and Microbiology. Before he started Usana in 1992, he spent 20 years developing and manufacturing 30+ diagnostic tests at Gull Laboratories to detect infections and certain autoimmune disorders.

Part of his job at Gull was to create a nutritional system to grow the healthiest and best functioning human cells that will survive in his laboratory. Cellular nutrition, after all, has always been his expertise, even before Usana.

When he realized that his parents and brother and so many other people are dying prematurely from chronic degenerative diseases, he decided to shift his focus from diagnosis to health promotion and disease prevention by supplying the nutrients that the human cells really need to function properly and to remain healthy.

By doing market research, he discovered that none of the nutritional supplements back then had the right combination, amount, and balance of nutrients to support the complex needs of human cells. He thought, if no facility in the whole world could manufacture nutritional products that could cater to the needs of the cells, then he would start one. That’s when he started Usana.

Dr. Wentz received the Albert Einstein Award for his Outstanding Achievements in Life Sciences in 2007.

He is also the founder of Sanoviv Medical Institute, which is a state-of-the-art, fully-licensed hospital that focuses on conventional, alternative, and integrative programs to help maintain your good health and treat a wide range of diseases.

He is also a humanitarian. Although he is a very successful scientist, it is his humanitarian works that bring him the most joy.

  • 5 Usana gives back to humanity.

Dr. Wentz’s humanitarian nature has made a big impact on the giving culture of Usana.

Usana and its associates are part of the True Health Foundation, which provides immediate and long-term global food relief for those in severe need. We also actively support the Children’s Hunger Fund and the Garden Towers initiative.

Usana Foundation

Garden Towers

Dr. Wentz and members of the Usana family also go to poor areas to personally help the people in need. We’ve been to corporate events and conventions where there’s always a big space for packing food and other relief items. We are also consistently given the chance (and reminded) to keep giving to those in need.

It’s truly a company with a big heart.

Usana True Health Foundation has helped millions of people in need.
