USANA head shot
Entering adulthood, I discovered that I had a genetic predisposition to heart disease. Like many, I had a choice: Succumb to pharmaceutical solutions for improving heart health OR take control holistically. In reviewing my options with my doctor, she encouraged me that as long as I was considering a natural approach to heart health, to ensure that my supplements and fish oil were pharmaceutical grade. I had no idea there was such a thing! And it is then……where USANA entered my life. Within weeks....my energy levels were greatly improved, I was sleeping better and taking control of my heart health. Today, I’m proud to say I’m drug-free—holistic all the way! A combination of exercise, low glycemic eating and incorporating USANA’s nutritional supplements has been instrumental to the health I enjoy today!!!
As a result, I chose to serve and educate others and help them achieve optimal health. It made perfect sense since I hold bachelor’s degrees in biology and education and became a wellness coach. We have one body…it’s time to give it your very best….including the top rated nutritionals in the world….because you deserve nothing less! Act now…don’t delay!!!!

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.
