This colorful illustration depicts the gut-brain axis and the role of functional postbiotics in this communication. It shows a detailed drawing of the brain connected to the intestines via the vagus nerve and blood vessels, highlighting the blood-brain barrier and intestinal barrier. Various postbiotic components such as SCFA (short-chain fatty acids), bacterial metabolites, peptides, and exopolysaccharides are illustrated interacting with the intestinal microbiota. The image explains systemic actions like neurotransmitter production (e.g., GABA, serotonin), immune system modulation, and neural signaling affecting mood and cognition, emphasizing reduced inflammation and beneficial bacteria in the gut.
