That sounds just like the one I have at home. That contains bacillus subtills which is in threelac and Streptococcus faecium which is part of the same Group D bacteria that threelac has as well.
Another good probiotic is lactobacillus plantarum. It was prescribed to me by my naturopath and it is specifically for IBS as plantarum is known to make is way past the all the acid to where it is needed. I have had great results with my probiotics but dont know which one is causing the results as I have the plantarum at work and the multi probiotic at night.
