This supplement was recommended by my doctor at a time when I was having a lot of gut issues. It has worked so well for me over the years, no matter my gut problem (constipation, diarrhea,stomach upset, etc.). I am so thankful to have something that can keep me on an even keel, especially now that research has shown how important the microbiome is to one's health.
