ISAPP is an association of academic and industrial scientists involved in basic and applied research on probiotics and prebiotics. The scientists participating in ISAPP have a common interest in generating high-quality scientific information for the probiotic and prebiotic fields and providing guidance for collaborative and multidisciplinary research. ISAPP is the only scientific organization dedicated specifically to probiotics and prebiotics, bringing together scientists from all pertinent disciplines, including food science, microbiology, immunology, biochemistry, and human and animal nutrition.

The organization raises the scientific credibility of the field by working with experts, conducting meetings, and facilitating high-quality research. As a scientific society, ISAPP focuses on advancing the science rather than promoting specific commercial products. Industry involvement is considered important to this organization, but no industry group or commercial entity dictates the activities or opinions of ISAPP.

ISAPP activities also benefit users of probiotic and prebiotic products by providing an objective, science-based voice that they can trust to help guide informed choices.



Individually and collectively, we endorse the proper use of the terms probiotics and prebiotics. We address misleading information and work closely with regulators to facilitate evidence-based approaches to applicable regulatory frameworks.

Advancing the Science

We encourage research by facilitating interactions among scientists in the field and publishing evidence-based summaries that highlight research gaps and promote the research that fills them. We encourage the funding of independent researchers by industry, foundations, and government in order to advance the science of probiotics, prebiotics, and fermented foods.


We disseminate scientifically accurate information on probiotics, prebiotics, fermented foods, and microbiome science to enhance understanding among researchers, students, regulators, and the general public. We also communicate with healthcare providers on evidence-based recommendations for the use of probiotics and prebiotics.
