Postbiotics
Beneficial compounds produced by probiotics, offering gut and immune benefits without live bacteria.
Also known as: Bacterial Metabolites • Heat-Killed Probiotics • Metabiotics
Overview
Postbiotics are bioactive compounds produced during fermentation by probiotic bacteria. They include short-chain fatty acids, enzymes, peptides, cell wall fragments, and organic acids. Unlike probiotics, postbiotics do not require live organisms, making them more stable.
