- Source of inulin: Prefer supplements derived from chicory root, Jerusalem artichoke, or agave, as these are well‑studied and provide consistent fiber quality.
- Purity & additives: Choose products with minimal fillers, artificial sweeteners, or allergens. A label that lists “100% pure inulin” or “no added sugars” is ideal.
