Postbiotics (General)

Postbiotics are bioactive compounds produced during the fermentation process of probiotic organisms, including heat-killed bacterial cells, cell wall fragments, short-chain fatty acids, and other bacterial metabolites. Unlike live probiotics, postbiotics do not contain viable microorganisms, which gives them advantages in terms of stability, shelf life, and safety profile. Research suggests that postbiotics may support gut barrier integrity, modulate immune responses, and exert anti-inflammatory effects through interactions with intestinal epithelial cells and immune receptors. Studies indicate that short-chain fatty acids such as butyrate, a well-characterized postbiotic, play a particularly important role in nourishing colon cells and helping regulate inflammatory pathways. While this is a relatively young field, emerging evidence points to postbiotics as a promising area of interest for supporting digestive and immune health.
