Sorry scarface... what I meant by that was if the body cannot provide an adequate environment for the pro-biotics they will not live there. Its like trying to live in a room without oxygen... its not going to happen.
However! if you body is ready to take on some bacterias... some pro-biotics... and they are able to repopulate some areas.... then you will recieve the benefits of the pro-biotics.
So I do suggest trying out pro-biotics every now and again to see if you get relief... :) but expecting pro-biotics to cure a health problem is not going to happen.
