Inulin

Tier-BPublic-ready7/3/2026

Glucose and metabolic health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

The 54.4 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the B tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.

Findings to review with care

Side effects reported for the ingredient alone are separated from findings involving another supplement or medication.

Side effects reported when this ingredient was used alone

Symptoms or adverse events reported in studies of this ingredient without another active ingredient.

Gastrointestinal Symptoms, Inflammatory Bowel Disease1 papers

Gastrointestinal negative effects due to inulin consumption were reported, such as gastrointestinal symptoms in humans and exacerbated inflammatory bowel disease in mice.Human studies · Systematic review

Gastrointestinal discomfort1 papers

Consumption of inulin at higher levels to meet daily fiber recommendations is associated with symptoms of gastrointestinal discomfort.Human studies · Systematic review

Positive combinations studied

Positive combination findings are separated by how the study compared the groups. This is not a recommendation to combine them.

Positive findings when used together

The combination had a positive result, but the contribution of each ingredient could not be separated.

CholineThe combination of inulin, choline, and silymarin reported obvious clinical beneficial effects on IBS-C patients regarding abdominal pain and bloating compared to diet alone.
