Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Bifidobacterium species have been studied for their potential role in managing allergic rhinitis, primarily due to their immune-modulatory effects. Several randomized controlled trials and meta-analyses have examined the efficacy of various Bifidobacterium strains (often as part of multi-strain probiotics) in reducing symptoms of allergic rhinitis. The underlying mechanism is thought to involve modulation of the gut microbiota and enhancement of the gut barrier, which may reduce systemic allergic responses by shifting the immune balance away from Th2-mediated allergic pathways toward a more regulated immune response.

A 2015 systematic review and meta-analysis (Peng Y et al., International Forum of Allergy & Rhinology) concluded that probiotics, including Bifidobacterium-containing products, may provide a modest benefit in improving quality of life and nasal symptoms in patients with allergic rhinitis, though the effect size was small and the included studies varied in probiotic strains and study design. Other clinical studies have shown mixed results, with some reporting significant reductions in symptom scores and serum IgE, while others found no significant effect compared to placebo. Most studies used combinations of Bifidobacterium with other probiotic species, making it difficult to attribute effects solely to Bifidobacterium.

Overall, while there is some scientific evidence supporting the use of Bifidobacterium for allergic rhinitis, the quality and consistency of the evidence are moderate at best, and further well-designed trials focusing on specific Bifidobacterium strains are needed.
