Currently, there is no scientific consensus on the efficacy of probiotics to treat irritable bowel syndrome (IBS). Authors of this paper attempted a meta-analysis of 56 studies on single-strain and multi-strain probiotics for the treatment of IBS, but trials were so heterogeneous when it came to probiotic concentration, duration of treatment, and methodology, that the meta-analysis was abandoned. Instead, they undertook a systematic review and found some evidence for the efficacy of single-strain probiotics (mostly bifidobacteria) in treating IBS.
