The original De Simone Formulation, developed through decades of scientific research in microbiota science.

A Legacy of Innovation in Probiotics


drdesimone.net is dedicated to preserving and distributing the original De Simone Formulation, while also developing and offering additional scientifically designed formulations for specific clinical and functional needs.

Founded on decades of research led by Prof. Claudio De Simone (MD, FAGA), our work reflects a broader commitment to evidence-based probiotic science and innovation.

A pioneer in microbiota science and probiotic research.


Prof. Claudio De Simone

A career dedicated to advancing microbiota research and probiotic science.

Academic and Professional Journey


Formerly professor of Infectious Diseases (Italy, University of L'Aquila), with a background in gastroenterology, allergology and clinical immunology, his academic career has been marked by a continuous commitment to research, clinical application, and regulatory standards in probiotic development.

Over the years, Prof. De Simone's work contributed to defining quality criteria for strain selection, formulation stability, and evidence-based use of probiotics in the dietary management of gastrointestinal conditions. This scientific approach remains at the core of the original De Simone Formulation today.

The Original Scientific Formulation

The De Simone Formulation


Introduced in the 1990s, the De Simone Formulation represents a milestone in evidence-based probiotic development.

Supported in more than 25 years by over 200 scientific publications and 80+ clinical studies, it has been extensively investigated in the dietary management of gastrointestinal conditions.

Its recognition by leading scientific societies, including European Crohn's and Colitis Organization (ECCO) and American Gastroenterology Association (AGA), reflects the rigor of its strain selection, formulation stability, and clinical validation.

Only products explicitly identified as containing the De Simone Formulation (CDS22-formula) correspond to that literature-defined formulation.

Scientific portfolio

Beyond a Single Formulation


While the De Simone Formulation represents a milestone in probiotic research and remains our flagship formulation, our portfolio is not limited to a single composition.

We develop and distribute additional proprietary formulations designed for specific applications and evolving scientific objectives.

Each formulation is defined by its own composition, intended use and technical specifications.

Preserving the original standards established through clinical research.

Commitment to Quality and Scientific Integrity


At DrDesimone.net, our commitment goes beyond distribution. We work to ensure that the original De Simone Formulation is preserved according to the scientific specifications defined during its development.

From controlled manufacturing processes to temperature-managed handling, every step reflects the standards of quality, stability, and authenticity that underpin decades of research.

Our goal is to maintain continuity with the original formulation while advancing new scientifically grounded developments, guided by evidence and delivered with responsibility.
