A Revolutionary Idea Grows

When Professor Claudio De Simone, M.D., began to develop his eight-strain, high potency probiotic, global recognition and appreciation of the human microbiome was only beginning to take root.

As decades passed and advances in technology gradually allowed scientists to more fully understand the complex community of microorganisms sharing a symbiotic relationship with human life, Professor De Simone worked alongside experts in inflammatory bowel disease, liver diseases, IBS, and oncology to perfect his invention.

What resulted was one of the most comprehensively studied probiotics on the market today: The De Simone Formulation.

There is Only ONE De Simone Formulation

The De Simone Formulation was previously sold under the name VSL#3®* by VSL Pharmaceuticals and its distributors.

When Professor De Simone severed his relationship with the company in July 2016, his former partners attempted to sell an untested version of the product, passing it off as the original formula, and neglecting to inform patients or physicians of the change.

In 2019, the distributors of VSL#3®* were found liable of false advertising by a federal court and ordered not to state or suggest a false continuity between VSL#3 and the De Simone Formulation.
