When creating these supplements, the best research matters.  With each ingredient, Dr. Wanda reviews dozens of recent published research articles.

We believe that you also have the right and responsibility to be educated in what is going on with your body as well as any supplement, therapy or treatment you receive.  To help you learn more, here are just a few of the most interesting ones to explore:
