Summary

My original recipe for SIBO Yogurt included three microbes chosen for their ability to colonize or germinate in the small intestine and produce bacteriocins, natural peptide antibiotics effective in killing the species of SIBO. The original formulation therefore specified L. reuteri, L. gasseri, and B. coagulans. However, B. coagulans proved to be unreliable in generating the high microbial counts we desire to overcome the trillions of invading fecal microbial species of SIBO. I therefo...

Episode Description

However, B. coagulans proved to be unreliable in generating the high microbial counts we desire to overcome the trillions of invading fecal microbial species of SIBO. I therefore replaced it with B. subtilis, a virtual powerhouse of a bacteriocin producer, producing up to 7 bacteriocins, thereby giving you greater power in pushing back invading fecal microbes in SIBO.

So in this episode of the Defiant Health podcast, let me get you acquainted with this powerful microbe that, I believe, can provide major advantages in your efforts to take back control over gastrointestinal and overall health.
