I am an old patient of IBS-C and did try many things. I live in Canada. I tried Total Restore by Dr. Gundri it worked very well and my symptoms were almost gone but again this started. The supplement is not easy to get here in Canada and it takes lot of time to get it online and it's expensive for me being Retired. Another friend suggested my L Glutamine amino acid tabs which also worked. Please share your experiences with IBS C.
