Probiotics are only part of the equation. To function optimally, they require the right environment—and more importantly, the right fuel. That’s where prebiotics come in.
Prebiotics are non-digestible fibers that selectively stimulate the growth and activity of beneficial gut bacteria. Unlike probiotics, which are live organisms introduced into the system, prebiotics act as substrates—feeding the native microbiota as well as any supplemental strains introduced through Biome.
Biome includes prebiotic components to support both colonization and persistence of its four primary strains. Specifically, it contains inulin-type fructans, which have been shown in research to enhance the growth of Bifidobacterium and Lactobacillus species—two of the dominant genera in this formula.
This prebiotic inclusion helps accomplish several key functions:
- Improved survivability and colonization of the included strains
- Selective fermentation, favoring beneficial bacteria over potentially pathogenic organisms
- Support for short-chain fatty acid (SCFA) production, such as butyrate, which contributes to gut barrier integrity and systemic immune modulation
- Promotion of microbial diversity, which is increasingly linked to long-term gut and metabolic health
By including both probiotics and prebiotics, Biome functions as a synbiotic—a formulation that combines both microbial strains and their preferred fuel source. This dual strategy enhances not only the initial delivery but also the sustainability of microbial balance within the gut over time.
