it is strange because you should not have other supplement together with P&B . Bentonite will take away all these vitamins , lactobacillus acidophilus etc along with the toxic waste inside your body. That's way it's recommended to have it an hour before or after meal/supplement. I have lived in Spain for few years but I would have thought it is diffcult to source these product. You can try http://www.total-cure.com They are based in Uk and I believe they will ship goods to Spain too.
