Multi Probiotic Spore + SBC Capsules (60 ct)

Multi-Probiotic® Spore + SBC by Douglas Labs is a next-generation probiotic formula that goes beyond conventional lactobacillus and bifidobacterium blends by combining two of the most clinically researched non-traditional probiotic types — spore-based Bacillus strains and Saccharomyces boulardii (SBC) — into a single, powerful 60-capsule formula designed for gastrointestinal and immune health.
Two Distinct Probiotic Types. One Comprehensive Formula.
Most probiotic supplements rely exclusively on lactic acid bacteria, which are fragile and often degrade before reaching the gut. Multi-Probiotic® Spore + SBC takes a more resilient, targeted approach with two fundamentally different and complementary probiotic categories:
Spore-Based Bacillus Strains
Spore probiotics are unlike any traditional probiotic species. Rather than requiring refrigeration or struggling to survive stomach acid, spore-based Bacillus strains:

Exist in a protective endospore state that shields them from heat, acid, and harsh digestive conditions
Germinate and proliferate directly in the small intestine, where they exert their greatest benefit
Support a healthy gut microbiome by selectively encouraging the growth of beneficial bacteria while crowding out opportunistic organisms
Provide durable, consistent GI support without the fragility of conventional strains

Saccharomyces boulardii (SBC)
S. boulardii is a well-researched probiotic yeast — not a bacterium — that offers a distinct and complementary mechanism of action:

Supports bowel comfort and regularity, particularly during times of stress or travel
Helps maintain healthy gut barrier integrity and mucosal defense
Provides immune-modulating activity within the GI tract
Resistant to antibiotics, making it particularly useful during or after antibiotic therapy

Key Benefits

Bowel Comfort and Regularity – Supports healthy, comfortable digestive function and normal stool consistency
Gastrointestinal Function – Promotes a balanced, well-functioning gut environment through complementary probiotic mechanisms
Immune Health – Both spore strains and S. boulardii exert immune-supporting activity within the GI tract, where a large portion of the body’s immune system resides
Superior Stability – Spore-based probiotics are significantly more stable than traditional strains, ensuring potency from capsule to colon
