Short answer: Inulin and resistant starch are fermented by gut bacteria, and fermentation produces gas. Increasing prebiotic fibre commonly causes bloating, wind or looser stools in the first week or two while the microbiome adjusts.
Why small doses mean a gentler adjustment
At 211mg and 100mg these effects are far less likely than with a full-dose fibre supplement — if you've had trouble with prebiotic products before, this is a gentler place to start.
Who should speak to a doctor before use
- You are pregnant or nursing
- You are under 18
- You are immunocompromised, or on immunosuppressant medication
- You have IBS, IBD, SIBO or another diagnosed digestive condition
- You are managing diabetes or any metabolic condition
- You take prescription medication of any kind
⚠️ Worth knowing: people with IBS or sensitive digestion often notice fibre effects more, because inulin is a FODMAP.
