Postbiotic potential of Lactococcus lactis CNCM I-5388 in alleviating visceral pain in female rat through GABA production: The innovative concept of the "active-GAD bag".

Irritable bowel syndrome (IBS) is a multifactorial disorder of the gut-brain axis, characterized by visceral hypersensitivity (VH). Psychobiotics, through GABA synthesis, are good candidates to alleviate gastrointestinal discomfort. Here, we analyzed the GABA-producer Lactococcus lactis CNCM I-5388 as an active-enzyme postbiotic to relieve VH mediated by psychological stress.
