Researched Nutritionals Corebiotic – 60 Capsules

What is CoreBiotic® and who is it for?

CoreBiotic® is a spore-based probiotic formula containing three fully sequenced Bacillus strains plus VitaFiber® prebiotic designed to support microbiome diversity and gut health. It’s formulated for individuals seeking to maintain healthy gut flora through a shelf-stable, room-temperature probiotic that doesn’t require refrigeration—making it ideal for travel, storage flexibility, and consistent daily use.

This formula is particularly suited to those who want targeted microbial support without the complexity of multi-strain blends, and who appreciate the science-backed specificity of each strain’s mechanism of action.

Why choose spore-based probiotics?

Traditional probiotics (Lactobacillus, Bifidobacterium) are fragile organisms that struggle to survive stomach acid and bile. Many don’t reach the colon alive, which limits their effectiveness. Bacillus spore-formers are fundamentally different: they’re dormant, hardy structures designed by nature to survive harsh environments. When they reach your lower GI tract, they germinate and colonise—establishing themselves rather than just passing through.

CoreBiotic® uses three distinct Bacillus strains, each selected for specific research-backed mechanisms. This isn’t a shotgun approach; it’s targeted microbial support. The addition of VitaFiber® prebiotic creates a synbiotic environment—you’re not just seeding organisms, you’re feeding them so they can thrive and support the broader microbial ecosystem.

How does it work?

Think of your microbiome like a garden. You can scatter seeds (probiotics), but without soil nutrients (prebiotics), they won’t take root. CoreBiotic® does both simultaneously: the three Bacillus strains are the seeds, and VitaFiber® is the nutrient-rich soil. When these spores germinate in your lower GI tract, they produce metabolites—short-chain fatty acids like butyrate—that feed your colonocytes (gut lining cells) and support the broader microbial community.

Spore Survival & Colonisation: Bacillus Coagulans (SNZ1969 and MTCC 5856) and Bacillus Subtilis (DE111®) are encased in protective spore structures. Unlike vegetative probiotics, they bypass stomach acid and bile intact, reaching the colon where they can germinate and establish. This is why they’re effective at lower CFU counts—survivorship matters more than total cell count.

Prebiotic Support: VitaFiber® (inulin) is a soluble fibre that selectively feeds beneficial bacteria while passing through undigested. This creates a preferential environment for the Bacillus strains and your existing beneficial flora, supporting microbial diversity and metabolic activity.

Metabolite Production: Once established, these strains produce short-chain fatty acids (especially butyrate) that support gut barrier integrity, reduce inflammation, and feed your colonocytes. This is the real mechanism of action—not just the presence of organisms, but the metabolic environment they create.

What can this support?

This formula provides nutritional support for:

General Microbiome Maintenance: For individuals seeking daily probiotic support to maintain healthy gut flora diversity and microbial balance as part of their wellness routine.

Post-Antibiotic Recovery: After antibiotic use, the microbiome needs microbial reseeding. Spore-formers are particularly useful here because they’re hardy enough to establish even in a disrupted gut environment.

Travel & Storage Convenience: Unlike refrigerated probiotics, CoreBiotic® remains stable at room temperature, making it ideal for travel, inconsistent storage, or anyone who struggles with refrigeration compliance.

Digestive Resilience: For those seeking to support normal digestive function and gut barrier health through microbial diversity and short-chain fatty acid production.

Microbiome Diversity: The three distinct Bacillus strains work synergistically to support a more diverse microbial ecosystem rather than dominance by a single organism.

Prebiotic-Inclusive Support: For individuals who tolerate and benefit from inulin-based prebiotics as part of their microbiome support strategy (distinct from CoreBiotic® Sensitive, which is prebiotic-free).

Common questions

Will I feel results immediately?
Microbiome changes are gradual. Most people notice shifts in digestive comfort and energy over 2-4 weeks of consistent use. The microbiome responds to sustained support, not acute dosing. Think of it like building fitness—consistency matters more than intensity.

Do I need to refrigerate CoreBiotic®?
No. Spore-based probiotics are inherently stable at room temperature. This is one of their major advantages over traditional probiotics. Store in a cool, dry place away from direct sunlight.

Is CoreBiotic® suitable for low FODMAP diets?
CoreBiotic® contains VitaFiber® (inulin), which is a FODMAP and may trigger symptoms in sensitive individuals. If you’re managing IBS or FODMAP sensitivity, consider CoreBiotic® Sensitive instead, which provides the same three Bacillus strains without prebiotic fibre.

Can I take this with other supplements?
Yes. CoreBiotic® works well alongside other digestive or microbiome-support supplements. If taking antibiotics, space CoreBiotic® at least 2 hours away from the medication to ensure the probiotic isn’t affected.

How many CFUs should I be taking?
CoreBiotic® provides 11 billion CFU per 2-capsule serving. With spore-formers, CFU count is less critical than strain selection and survivorship. The three strains in this formula are chosen for potency and research backing, not quantity alone.

Is CoreBiotic® vegan and allergen-friendly?
Yes, it’s vegan and free from milk, eggs, fish, shellfish, peanuts, wheat, and soy. It does contain tree nuts (coconut oil, as MCT). Always check the label if you have tree nut sensitivity.
