I wasn't sure of the validity of that report, but it did seem that with FOUR people responding in the same manner, there was something to it. (Some might call it a "phantom" report, but I'm sorry I can't locate it. I probably will at some point.)
I've not been impressed with Probiotic supplements. Have heard you can even get the wrong bacteria. What I know that DOES work is to eat Inulin containing foods/herbs for your Bifidus bacteria.

And Cereal grasses are supposed to have the Acidophilus.
