Prebiotic Fiber (Inulin/FOS)
Your gut bacteria ferment it — and gas is a direct byproduct of that same fermentation.
Say that in clinical terms
Rapid fermentation of inulin/FOS by colonic bacteria produces gas (CO2, H2, methane) as a direct byproduct — the same fermentation that improves stool frequency is what causes gas.
How strong is the research?
No Benefit evidence
Mild bloating was reported significantly more often as an adverse event on FOS versus placebo (OR 10.36, 95% CI 3.32-33.23).
