Inulin / FOS (Prebiotics) and Inulin / FOS (Prebiotics) for IBS symptoms
Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.
Compound or practice
Inulin / FOS (Prebiotics)
Fermentable fibers that feed beneficial bacteria and short-chain-fatty-acid production — real but gassy, and rough on sensitive guts.
Grade C2 graded outcomesrevised Jul 10, 2026

Graded in both
Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.
