Instagram video sparks interest in postbiotics

A video uploaded to Instagram on October 30, 2026, by the account les.conseils.pharma.de.lea has reignited public interest in postbiotics. The video uses an analogy to explain the intestinal ecosystem, comparing probiotics to a team, prebiotics to their meal, and postbiotics to the byproducts of their work.

Postbiotics explained through a simple analogy

The video highlights that the microbiome involves not just the bacteria themselves but also the molecules they produce, especially when fermenting dietary fibers. Among these molecules, short-chain fatty acids are of particular interest for their potential role in interactions between diet, the microbiome, and the body.

Scientific definition of postbiotics clarified

According to the International Scientific Association for Probiotics and Prebiotics (ISAPP), the term "postbiotic" has a specific meaning. It refers not to everything bacteria produce but to preparations of inactive microorganisms or their components that have demonstrated health benefits.

Importance of accurate terminology

The distinction between postbiotics and microbial metabolites is crucial. Using a trendy term can create the impression that a product has scientifically proven health benefits when such claims may not be supported by evidence.
