I just talked to my friend and she no longer takes the Kijimea but when she has a diarreha problem goes to this Wafer from Standard Process....Her issues are mostly constipation but goes the other way too. I don't know what is worse for you.
Standard Process - Lactic Acid Yeast™
Now one could call SP and ask they if it's good for both D and C IBS.
I don't believe I have IBS necessarily but have run constipation issues a lot of my life. I work on that to keep regular and some times 2-3 BM's daily...
I also take 30Billion probiotics daily, and just bought a new product that is 25Billion as the one I was getting is no longer available.
