I just started on this product not quite a month ago and I am already feeling a beneficial difference. It is so hard to tell if some products ever do anything at all. And with any of the "dopohilus" supplements, it is important to know that you have chosen something that can survive stomach acid and actually make it to the intestines so it can friendly up the territory. I absolutely know this product is doing that and I am deeply grateful to iHerb for making this both available and affordable.
