Acacia Fiber (Gum Arabic)
Also known as: gum arabic, gum acacia, Acacia senegal, Acacia seyal, arabic gum, Fibregum
Acacia fiber is the dried sap of Acacia senegal and Acacia seyal trees, a highly branched arabinogalactan polysaccharide that dissolves completely in water with almost no viscosity. It ferments slowly along the length of the colon, which is why it is one of the best-tolerated prebiotic fibers at practical doses. A dose-ranging trial in healthy volunteers found bifidogenic effects at 10 g per day with good tolerance. It is used in gut-health and fiber powders, as a low-FODMAP-friendly fiber, and as an emulsifier and capsule-friendly bulking agent.
Research summary
Slowly fermented arabinogalactan; studied for increases in bifidobacteria and lactobacilli and for gentle effects on stool regularity.
Dosage
Daily amounts, of compound.
| Lowest studied | Typical range | Highest studied | Upper limit |
|---|---|---|---|
| — | 5–10 g | — | — |
Take 5–10 g daily, mixed into water or a beverage; the 10 g dose is the level with the clearest bifidogenic evidence. Well tolerated even without a ramp-up period. Dose_min left null because the lowest effective dose has not been established in a supplement-format trial.
Standardization: ≥90% soluble fiber (dry basis); spray-dried, low viscosity
Source material: tree gum exudate (Acacia senegal / seyal)
Format suitability
- Capsule
- Powder
- Tablet
- Softgel
- Gummy
- Liquid
Neutral taste, fully soluble, non-thickening; ideal for stick packs and drink mixes. Gram-level doses make capsules impractical.
Formulation notes
May slow absorption of some medications when taken at the same time; advise spacing. Low fermentation rate means minimal gas.
