postbiotic

Dead probiotic benefits

Postbiotic refers to beneficial compounds produced by probiotic bacteria during fermentation—the metabolic byproducts rather than the living organisms themselves.

These include enzymes, organic acids, and cell wall fragments that may support gut health.

The term appears in nutrition and supplement marketing: postbiotic supplements, foods rich in postbiotics.

Compare with prebiotic (food for beneficial bacteria) and probiotic (the living bacteria).
