Bifidobacterium Longum for Constipation Relief

Insufficient evidence 2 studies

Research suggests that Bifidobacterium longum may offer benefits for constipation relief, though the current evidence base is limited in scope. The most directly relevant study — an animal experiment comparing six Bifidobacterium species in mice with drug-induced constipation — found that B. longum subsp. longum was the only strain to meaningfully improve constipation symptoms, an effect the researchers linked to its ability to dissociate bile salts and favorably shift gut microbiome composition and metabolite levels. The second study, which examined gut microbiota in a mouse model of a rare genetic neurological disorder, did not address constipation directly and contributes little to evaluating B. longum for this purpose. Overall, while the preclinical findings are intriguing, the absence of human clinical trials means it is too early to draw firm conclusions, and readers should view these results as preliminary.
