The science behind Protandim is different and unique because LifeVantage Corporation doesn't pay for it. In the world of research, this means that the product and its science must be so compelling that Ph.D.s from universities around the world want to study it and want to spend their own time and money doing it. LifeVantage has a product other people are paying to study! That is unheard of, especially in the supplement industry.
