Evidence on the Preventive Effects of the Postbiotic Derived from Cow’s Milk Fermentation with Lacticaseibacillus paracasei CBA L74 against Pediatric Gastrointestinal Infections

Postbiotics are commonly defined as preparations of inanimate probiotics and/or their cellular components and/or their metabolites/end products that confer health benefits on the host. They have been suggested as a promising strategy to limit infectious diseases. Emerging evidence support the efficacy of the postbiotic derived from cow’s milk fermentation with the probiotic Lacticaseibacillus paracasei CBAL74 (FM-CBAL74) in preventing pediatric infectious diseases. We aimed at reviewing the evidence available.
