Are Visbiome and Vivomixx the Same? Unpacking the De Simone Formulation

3 min read

Before 2016, a highly researched probiotic formula known as the De Simone Formulation was sold under the brand name VSL#3. This historical fact is the root cause of the confusion surrounding the products currently known as Visbiome and Vivomixx, which both contain this specific, multi-strain probiotic blend.

Quick Summary

Clarifying the confusion between Visbiome and Vivomixx, this article reveals their shared origins in the patented De Simone Formulation. It details the history behind the branding changes, comparing the two products based on their identical bacterial blend and high potency.

Key Points

  • Shared Origin: Both Visbiome and Vivomixx contain the identical, original probiotic formula developed by Professor Claudio De Simone.

  • Branding Not Formula: The difference between Visbiome and Vivomixx is geographic branding, not the product's composition; Visbiome is for the US/Canada, Vivomixx for Europe/other regions.

  • Distinction from New VSL#3: The original formula was once VSL#3, but the current VSL#3 uses a different formulation and is not the same as Visbiome or Vivomixx.

  • Clinically Supported Blend: The eight-strain De Simone Formulation is backed by extensive clinical research for specific digestive conditions.

  • Critical for Efficacy: For patients needing a clinically proven probiotic, verifying that the product contains the authentic De Simone Formulation is crucial for achieving expected therapeutic outcomes.

  • Cold-Chain Delivery: Both Visbiome and Vivomixx require refrigerated storage and shipping to preserve the viability and potency of their live bacterial cultures.

A Tale of Two Names, One Formula

The question, "Are Visbiome and Vivomixx the same?" is common for consumers seeking the original, high-potency De Simone Formulation probiotic. The short answer is yes: Visbiome (sold in the U.S. and Canada) and Original Vivomixx (sold in Europe and other regions) both contain the exact same proprietary blend of eight bacterial strains. The differentiation lies entirely in regional branding and distribution rights, which were established following a split from the original manufacturer of VSL#3.

The Historical Timeline: VSL#3, Vivomixx, and Visbiome

The story begins with Professor Claudio De Simone, a medical doctor and immunologist who developed a unique, high-concentration probiotic formula in the 1990s. This formulation was originally licensed and sold under the brand name VSL#3, which gained significant recognition and clinical support for its effectiveness in managing conditions like ulcerative colitis and pouchitis.

A dispute over manufacturing and intellectual property rights led to the termination of the licensing agreement. Following this separation, Professor De Simone retained the rights to his original formulation, leading to new branding:

  • Visbiome: Licensed for sale in the United States and Canada.
  • Vivomixx: Distributed internationally by Professor De Simone's company, Mendes S.A., particularly in Europe.
  • VSL#3 (New Formulation): The former licensee continued to sell a product under the VSL#3 name, but it no longer contained the original De Simone Formulation.

Identical Formulations, Different Packaging

Visbiome and Original Vivomixx share the same ingredients and deliver the same eight bacterial strains at the same high concentrations. They are manufactured to the same quality standards and require cold-chain storage.

Both products contain the following shared strains:

  • Lactobacillus acidophilus
  • Lactobacillus plantarum
  • Lactobacillus paracasei
  • Lactobacillus delbrueckii subsp. bulgaricus
  • Bifidobacterium longum
  • Bifidobacterium breve
  • Bifidobacterium infantis
  • Streptococcus thermophilus

Key Distinction Represents the continuation of the original formula Represents the continuation of the original formula A different product with the same name

Why the Correct Formula Matters

For those managing specific gastrointestinal conditions, the precise bacterial composition is paramount. The therapeutic benefits documented in clinical studies are linked to the specific balance of the eight strains in the De Simone Formulation. A different blend may not yield the same clinical outcome. For instance, a meta-analysis showed the De Simone Formulation was helpful for ulcerative colitis, emphasizing the need for the correct blend. This was central in a legal case where ExeGi Pharma sued a competitor for false advertising regarding their product's similarity to Visbiome.

Conclusion

Visbiome and Vivomixx are different brands sold in different regions, but they contain the same, original De Simone Formulation. The critical distinction is between them and the current version of VSL#3, which uses a different formulation. Consumers seeking the probiotic with proven clinical history should ensure they purchase a product with the authentic De Simone Formulation, choosing either Visbiome or Original Vivomixx depending on location. Making the right choice involves understanding the history and focusing on the scientifically validated formula.
