I totally agree. I have said this before in posts - the effects of probiotics are only transient (in my experience). How can they even begin to repopulate something the size of the human colon? I have even wondered just how "safe" some these man-made bacterias/probiotics are which are sold to us as supplements? I have come to the conclusion that after almost 20 years of suffering dysbiosis caused by Antibiotics that I will be forever at the mercy of a poorly function gut, depleted in good bacteria wiped out from years of over prescibed and unnecessary Antibiotics . I look forward to hearing some of your suggestions afterall nothing else has worked...probiotics especially. By the way I did read that Biocare a UK company derived their probiotics from human origin but even so they still havent done much for me (and also how safe is this).
