Spore-Based Probiotics (Bacillus)
Shelf-stable spore-forming bacteria that survive stomach acid and colonize the gut effectively.
Also known as: Bacillus Probiotics • Soil-Based Organisms • SBO Probiotics
Overview
Spore-based probiotics from the Bacillus genus form protective endospores that survive stomach acid, heat, and antibiotics. Clinical research supports their ability to reduce intestinal permeability and support microbiome diversity.
Key Benefits
Survives Stomach Acid
Endospore coating protects bacteria through the entire GI tract.
Reduces Leaky Gut
Clinical trial showed 60% reduction in intestinal permeability markers.
Microbiome Diversity
Supports growth of beneficial bacteria and increases microbial diversity.
Shelf Stability
No refrigeration required; stable for years at room temperature.
