The human gut microbiome contains over 100 trillion microorganisms that produce neuroactive compounds, including neurotransmitters like serotonin, GABA, and dopamine. Clinical studies have shown that disruptions in gut bacterial populations correlate with mood disorders, while specific probiotic strains can modulate neurotransmitter levels and influence behavior through the gut-brain axis.

The challenge lies in identifying and delivering viable probiotic strains that can survive gastric conditions while producing therapeutic levels of neuroactive compounds at their site of action.

This page brings together solutions from recent research—including nano-encapsulated GABA-producing probiotics, engineered microorganisms for serotonin production, specific Lactobacillus strains for behavioral disorders, and combination approaches using probiotics with mood-regulating compounds. These and other approaches focus on developing stable formulations that can effectively influence mood and behavior through gut-brain pathways.
