Bifidobacterium species are increasingly studied for their potential to support cancer patients undergoing chemotherapy, particularly in minimizing gastrointestinal side effects such as diarrhea, mucositis, and dysbiosis. Scientific evidence, primarily from preclinical animal models and a growing number of small clinical trials, suggests that supplementation with Bifidobacterium can help maintain gut barrier function, modulate immune responses, and restore microbial diversity disrupted by chemotherapy. For example, some randomized controlled trials have shown that patients receiving probiotic mixtures containing Bifidobacterium experience reduced incidence and severity of chemotherapy-induced diarrhea and mucositis, with noted improvements in gut microbial balance. The presumed mechanisms include enhancement of mucosal integrity, competitive exclusion of pathogenic bacteria, and modulation of inflammatory cytokines.

However, while the results are promising, they are not yet definitive. Most studies are limited by small sample sizes or use multi-strain probiotics, making it difficult to attribute effects solely to Bifidobacterium. Large-scale, well-controlled clinical trials are needed to establish efficacy, optimal strains, and dosing. Major cancer organizations do not yet universally recommend routine probiotic use during chemotherapy, though they acknowledge the potential. In summary, there is a moderate and growing body of scientific evidence supporting the adjunctive use of Bifidobacterium to reduce certain chemotherapy side effects, but more robust clinical validation is needed.
