• Alleviates Asthma

Bifidobacterium breve B632, used alongside Lactobacillus salivarius LS01, supports asthma improvement primarily by enhancing gut barrier integrity and regulating mucosal immune responses along the gut–lung axis. B632 promotes regulatory T-cell activity, increases IL-10, and supports epithelial barrier function, which reduces allergen translocation and systemic inflammatory signalling implicated in asthma exacerbations. It also influences microbial composition by suppressing dysbiotic species associated with respiratory infections and allergic airway disease. 

When paired with LS01, B632 contributes to a synergistic immunomodulatory effect that reduces airway hyper-responsiveness and improves overall immune tolerance without altering eosinophil counts or spirometry outcomes.
