I'm doing Oxypowder , Parastroy, and probiotics now. To me, I don't see any conflict in doing those together. I think the only catch is that if I have parasites, I may not see them since my stools are watered down from the Oxypowder . I don't think I have parasites, but I'm still doing the parasite cleanse anyway, just in case. I'm using Garden of Life Primal Defense Probiotics. I will continue to do those for a while, even after I finish the Oxypowder and Parastroy.
