In this masterclass, you’ll learn:

• What 49 studies found, and what they didn’t. Why some results look remarkable on paper, why SIBO doctors often see more modest help in practice, and how to read the research without getting swept up in it.
• Probiotics matched to your SIBO type. The strains studied for hydrogen, methane, and hydrogen sulfide SIBO, and where each one is available.
• Probiotics matched to your symptoms. What the research and experienced clinicians point to for constipation, diarrhea, pain, bloating, food reactions, and the anxiety that so often travels with SIBO.
• Probiotics alongside antibiotics or herbal antibiotics. What happened in the studies when the two were combined, including the effect on side effects.
• Why a probiotic can make you feel worse. Histamine, extra gas from “cross-feeding,” and the prebiotics hidden in many formulas. How to read the other-ingredients list, why going slow helps, and the types sensitive and histamine/MCAS patients often tolerate.
• The die-off question. Dr. Siebecker asks whether some people stop a probiotic too soon when symptoms flare, and when a flare is a clear reason to stop.
• After treatment. What SIBO doctors reach for when leftover symptoms linger, and in the months after treatment ends.
• Probiotic bombing for stubborn cases. Dr. Jason Hawrelak’s high-dose approach and who it’s meant for, plus a detailed spore-probiotic case from an experienced SIBO practitioner.
• The brand names. Why the strain code on the label is worth checking, which products match the studied strains, the favorites of the SIBO doctors Dr. Siebecker surveyed, and her own pick for sensitive patients.
