Postbiotics are beneficial metabolic byproducts released after cellular lysis, such as peptides,

polysaccharides, teichoic acids, enzymes, organic acids, and cell surface proteins, secreted by
probiotic bacteria. Postbiotics are generally produced by certain genera of the Lactobacillaceae

family and strains of the Bifidobacterium genus, as well as lactic acid bacteria such as Pediococcus,
Streptococcus, and Lactobacillus.

Postbiotics have anti-inflammatory, antioxidant, antihypertensive, antiproliferative,
antimicrobial, hypocholesterolemic, and immunomodulatory effects, or they synthesize metabolites

and products from microbial enzymatic activity on the food matrix.

Postbiotics exhibit multifaceted mechanisms in terms of their health effects. Postbiotics
possess various properties, including regulation of intestinal microbiota and epithelial barrier function
through bacteriocin production; modulation of immune cell responses through the production of

metabolites such as peptidoglycan, lipoteichoic acid, and exopolysaccharide; and inhibitory effects
against pathogens through their antibiofilm properties. Because postbiotics do not contain live
microorganisms, the risks associated with their consumption are reduced.

The use of postbiotics in clinical practice is still a developing field. Compared to probiotics, they

offer advantages such as longer shelf life, lower cost, and ease of standardization. Postbiotics have
the potential to play a significant role in personalized nutrition and therapeutic approaches in the
future.
