Why this formula

Traditional probiotics (lactobacillus, bifidobacterium) struggle to survive stomach acid — most strains never reach the colon alive. Spore-based probiotics (bacillus species) form a protective endospore until they hit the lower intestine, then activate. We've selected five strains with the strongest published evidence for digestive comfort, immune support, and gut-barrier integrity. Room-temperature stable — no refrigeration.
