I take b12 , but don,t know as it helps be. I B guard helps me more than anything, along with a probiotic. These two really help.

are you IBS-C or IBS-D? which probiotic are you using?
I have IBS-C and am on a probiotic (Culturelle) as well but can't really tell if is helping me yet..

When I take a B12 shot once a month and it has no effect on my constipation whatsoever the B-12 pills do not work unless they're the ones you put under your tongue those sublingual and they aren't going to help with constipation I will tell you that I've been taking B12 shots for about 15 years

I have tried, all sorts of Probiotics, nothing has seemed to help . I suffer from IBD-C . At the present time, taking Trulance, which helps.. Hope you find some relief. Also bloated all the time.

I recently started taking b-22 and vitamin d.not sure if it is helping or not.What is there to lose.
