Try to find this product in Europe. This is a Russian Prebiotic (made in Brazil also) that is considered one of the best Prebiotics so far. I have more information about it including comparative charts about the colonic bacterial ecology before and after taking it for a month. It is incredible how the flora growth taking it. ( a lot more than taking FOS or Inulin ) I will try to find the papers in my archives. By now, here it is.
