Acacia Fiber for Constipation: How to Use It Properly
How Hashab gum arabic (acacia fiber) supports regular bowel movements, what a 2024 trial found about stool frequency, the dose, how to use it, and when to see a doctor.
How soluble fibre helps constipation
Soluble fibre holds water in the gut, softens stool, and feeds beneficial bacteria that produce short-chain fatty acids supporting the colon. Hashab gum arabic is easy to dissolve and almost tasteless, which makes daily use easy to stick with.
What the research found
In a randomised trial of 180 adults with IBS with constipation, 10 g of acacia fiber daily for 4 weeks significantly improved stool frequency compared with placebo.
How to use it for constipation
- Week 1: half a sachet (about 5 g) a day.
- Then: one sachet (10 g) a day.
- Mix in a large glass of water and drink more water through the day. Fibre without enough fluid can make constipation worse.
- Continue for 3–4 weeks before judging the result.
Habits that help
- Daily movement, even a 20–30 minute walk.
- A regular toilet time, ideally after breakfast.
- Fruit, vegetables and whole grains with meals.
- Don't delay the urge to go.
