I have been reading a lot into probiotics but havent started it yet. recently saw this thread by david where people gave their opinions about probiotics. I searched the web and came to know about kefir. In my part of world it is not really known..but what I can understand from my research it is a healthy probiotic and helps in IBD..can someone tell more about it or anyone who has had good experience with it in crohns ? how do i get it ?
