Tosca Headshot 4-2012
I have been a holistic health care professional helping people understand how to take responsibility for their own health through proper nutrition, for over 35 years. Although I am a graduate of medical school, I always preferred an all natural approach of nutritional consultation and education. Recommending Nutritional Supplements never crossed my mind for two reasons: 1. We were taught absolutely nothing about good nutrition in Medical School; and 2. I truly believed that if you were eating a good variety of foods, mostly plant based and raw then you did not need supplements. When I finally gave USANA a try I was really surprised! In a week's time I began sleeping better, had my energy back and was keeping up with my 20 year old even at the gym!
Within just two weeks my husband lost what he called his foggy brain, was bouncing out of bed in a good mood every morning and remembering to take everything he needed for the day on his way out the door instead of making three trips back for the things he forgot. And I was able to enjoy other such success stories from my patients who were not stubbornly refusing to take supplements. I found that because USANA’s vitamins use micro-nutrients to nourish our cells and fulfill our most basic cellular-biological needs, they fill the gap of nutrients that poor soils and genetically modified foods and herbs lack. They simply enhanced any dietary treatments I would prescribe. It’s been 5 years since I was introduced to these supplements and I’ve been working with them ever since.

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.
