The SIBO Yogurt Game-Changer That Dr. Davis Switched To
If you're still using B. coagulans in your SIBO yogurt, you're working with outdated science. Dr. Davis replaced it with B. subtilis HU58 for good reason: coagulans was a fermentation diva that gave wildly inconsistent results. HU58? It's the reliable workhorse that produces 7 different bacteriocins (versus coagulans' measly 1-2) PLUS surfactants that literally dissolve pathogen biofilms. This is the upgrade your gut has been waiting for.
Why This Replaced B. Coagulans in the 2025 Protocol
- 7 bacteriocins vs 2 — more antimicrobial firepower than the original
- Biofilm destroyer — produces surfactants that break down pathogen shields
- 100% survivability — spore-forming means it laughs at stomach acid
- Consistent fermentation — no more mystery batch failures
- Broader spectrum — works against gram-positive AND gram-negative bacteria
- 60 capsules — enough for 60+ yogurt batches
The Two-Jar Protocol Reality Check
Here's the catch: HU58 doesn't play nice with L. reuteri and L. gasseri in the same jar. It reproduces 50% faster and would dominate the ferment. So now you're making two yogurts: your familiar L. reuteri blend (36 hours at 100-106°F) and a separate HU58 yogurt (24 hours at 90-100°F). Yes, it's more work. But when community members report "finally, every batch works!" and "my gut feels calmer than ever," that extra jar suddenly seems worth it. Read the full protocol update here.
