Probiotics and Gut Health: Building Your Body's Second Brain

The human gut hosts approximately 100 trillion microorganisms, with a gene count 150 times that of the human genome. Gut microbiota communicate bidirectionally with the central nervous system via the gut-brain axis, influencing mood, cognition, and behavior. Supplementing with specific probiotic strains can strengthen the gut barrier, modulate immune responses, alleviate irritable bowel syndrome (IBS) symptoms, and may even provide supportive benefits for anxiety and depression.
