Lactobacillus helveticus R0052 combined with Bifidobacterium longum R0175  works through several coordinated mechanisms that influence the gut–brain axis. First, both strains reduce inflammation-driven neurochemical disruption by decreasing pro-inflammatory cytokines and supporting IL-10 upregulation, which protects serotonin and dopamine pathways from cytokine-induced depletion. 

They also reinforce gut barrier integrity and competitively suppress stress-amplifying gut bacteria, reducing inflammatory signalling into the central nervous system. The strains modulate afferent vagus nerve signalling, improving emotional regulation and reducing amygdala-driven stress responsivity. 

Additionally, they attenuate hypothalamic–pituitary–adrenal (HPA) axis overactivity, leading to reduced cortisol production. Together, these effects stabilise neurotransmission, lower visceral stress signalling, and improve behavioural and emotional processing.
