Amy Koo, Director

Welcome to USANA, where we manufacture the highest-rated nutritional supplements and world-renowned weight management and personal care products.

Hello, I am Amy Koo and my family and I have enjoyed the health benefits of these products for over ten years.  I have also enjoyed the side income from sharing these products with others.
My purpose in developing a business with USANA was to set myself up with a back-up plan to the uncertainties of corporate life.    In doing so, I not only gave myself tax advantages, but I created true health for myself, husband, children and all our family.  

I encourage you to take advantage of all USANA has to offer -- both in terms of all the health benefits and the potential of building an international business you can run from home.

Take the Health Assessment to find out which products would be of most benefit.  Then, let's talk about how you can turn getting healthy into creating extra income as well.


“I always talk to my friends and family about USANA. Together, we’re on a mission to make the world a happier, healthier place.”
—Dr. Mehmet Oz

USANA offers products to customers through direct selling, which means that individuals just like you can own their own USANA business. And yes, direct selling is different. It's not the status quo. But USANA understands direct selling just as much as it understands nutritionals. Which is, they get it. In fact, they're the best at what they do.

USANA is a Trusted Partner and Sponsor of The Dr. Oz Show

USANA's Foundation

We were founded by a scientist—not a corporate suit.

USANA's founder, Myron Wentz, Ph.D., is an internationally recognized microbiologist, immunologist, and pioneer in infectious disease diagnosis. In 1974, he founded Gull Laboratories to develop viral diagnostics, and his greatest successes during this time included the first commercially available diagnostic test for Epstein-Barr virus, better known as the virus that causes mononucleosis.

But success was never Myron Wentz' only aim. Instead, he centered his life around a dream of a world free from pain and suffering. A world free from disease. And he founded USANA to help further his dream by providing people all over the world with the most advanced supplements science can produce.

This is why USANA is a company based on continuous product innovation. This is why they have stringent manufacturing processes, participate in ongoing scientific research, and have an insatiable drive to produce exceptional products. This is why USANA is trusted by professional athletes and Olympians, and also everyday people who believe health is a vital part of a long, happy life.

This is why USANA is not just another direct selling business.
