Evidence-backed FAQ
Do probiotics help IBS?
Direct answer
Pooled randomized trials suggest some probiotic strains may improve IBS symptoms such as abdominal pain and overall symptom severity, but the effect is strain-specific rather than a general property of all probiotics.[1], [2]
What the evidence shows
Meta-analyses found that different strains or mixtures ranked differently for pain, bloating, symptom severity, and quality of life.[1], [2]
Important limitations
The trials varied widely in strain, formulation, dose, duration, and IBS subtype. Pooled averages cannot predict whether a specific product will help a specific person.[1], [2]
