Probiotics enhance intestinal barrier function and modulate the immune system by increasing adhesion to the intestinal mucosa, producing antibacterial substances, and reducing pro-inflammatory cytokines.
Understanding that probiotics work by strengthening your gut lining and calming inflammation helps explain why they might help with digestive issues. It is not just about 'adding good bacteria' but about how those bacteria interact with your existing gut environment to protect you.
The advancement of the epithelial barrier, increased adhesion to the intestinal mucosa, production of antibacterial substances, competitive exclusion of pathogens, simultaneous suppression of bacterial adhesion, and modulation of the immune system are some of the main mechanisms of action of probiotics
Why this rating
The paper cites multiple references ([87-91]) for these mechanisms, indicating a strong scientific consensus on the biological pathways, even if clinical outcomes vary.
