Mechanism of action

C. butyricum is a gram-positive, anaerobic bacterium that ferments carbohydrates to produce butyrate, which serves as an energy source for colonocytes and strengthens the intestinal epithelial barrier. Butyrate also promotes the differentiation of regulatory T cells and reduces pro-inflammatory cytokine production, thereby restoring dysbiotic microbiota balance and reducing intestinal inflammation.
