The best probiotics for bloating are specific strains studied in IBS, where meta-analyses found some probiotics improved bloating and overall symptoms, though evidence quality is low and results vary. Try one product with a named strain for about 4 weeks. Bloating often has other causes worth addressing, such as constipation, certain foods or swallowed air.
