Probiotics for IBS
Probiotics are microorganisms that supplement the gut's natural bacteria, helping to create balance. There is not strong evidence that probiotic supplements help alleviate IBS symptoms like abdominal pain, bloating, and bowel movement irregularity. However, probiotic supplements from reliable sources won't do any harm and some people report being helped.
If you go to just about any store you'll see the shelves full of probiotic yogurts and milk. Most studies of probiotics and IBS don't differentiate between bacterial strains and doses, which makes it hard to know which probiotic will work for you.
The problem with relying on probiotics is that they do not rewire your brain's interpretations of signals coming from the gut. If there is an imbalance in the microbiome, it is possible that probiotics can help, but there is little evidence that probiotics have a significant effect on IBS.
