I should, but I always forget to take them. I am not right now.
There haven't been many isolated strains shown to be effective for some symptoms of IBS, but this is one strain. Some people are helped with gas with them and perhaps then pain.
I can't really recommend one other then to say just try one and see if it helps. There are a lot of different kinds, like activa yogurt , which my wife who also has IBS eats once in a while, she can go back and forth and it does seem to help her some. The new phillips colon health that Dana just tried and liked perhaps.
The gut bacteria are different in different people and even where they live. Someone in oregon doesn't really have the same as in say florida, because it helps protect us to our own environments. Foods, and even stress can mess with it all and change them.
It could be worth trying though and is not likely to hurt anything.
