View Full CurriculumWhy SIBO Mastery?
SIBO science has advanced more in the last two years than in the last twenty.
New research shows distinct microbial drivers behind SIBO, IMO, and intestinal sulfide overgrowth — and modern breath test interpretation has become more nuanced. Many practitioners tell us they feel unsure how to interpret complex breath test patterns, stuck with methane-dominant or relapsing cases, overwhelmed by rapidly changing SIBO research, or isolated when navigating complex gut presentations.
The SIBO Mastery Program was created to address exactly this — with structured training, practical tools, and now ongoing monthy mentorship.

What SIBO Mastery Does for Your Practice
The SIBO Mastery Program is designed to be practical and clinically applicable. It helps you work confidently with complex SIBO, IMO, and ISO cases, interpret breath tests quickly and clearly, use structured, evidence-based treatment pathways, reduce relapse with updated prevention strategies, save time keeping up with emerging SIBO research, feel supported in live Q&A sessions, rather than isolated when cases become challenging.
In this short overview, Dr Nirala Jacobi explains how SIBO Mastery helps practitioners move from uncertainty to confidence when managing SIBO, IMO, and ISO.
Why Practitioners Love It
Dr Allison Siebecker
"Dr. Jacobi's lectures are excellent. She blends research, clinical experience, new thinking, and practical application into all of her teaching. I always learn from her and greatly appreciate her contributions to our field of SIBO."
Dr Steven Sandberg-Lewis
"Dr. Jacobi is a masterful teacher. Her lecture style is thorough, well organized and always filled with "aha!" concepts and treatments. Her extensive knowledge of small intestine bacterial overgrowth, its diagnosis and natural treatment through botanical medicine and diet is appreciated worldwide. Her contribution to the field by the creation of the Bi-phasic diet in its various versions is a major gift to those suffering from this common malady."
"I want to thank Nirala for creating a way for people to find a SIBO-literate practitioner who has taken the comprehensive SIBO Mastery Program. I would say that at least half of my clients find me via The Sibo Doctor database. I also love the use of support materials such as the 'What Caused My SIBO' questionnaire, and the beautiful, revised Bi-Phasic Diet ebook. This is invaluable."
Louise Beach - Nutritionist (New York)
“Excellent, excellent course!! I've been using the bi-phasic diet this year and my patients are so much more compliant and have commented on how much easier it is to follow having clearly defined stages and serving sizes etc. Due to the overwhelming positive feedback from the diet, I had to do the mastery course, it's genius. The bonus protocol document is such a game changer for quick reference."
Karen (California)
“Since SIBO Mastery, my diagnostic confidence and structured approach have cut relapse rates significantly.”
