Acacia fiber (prebiotic)
Tier 1 — strong evidence · Prebiotic · IBS · Cholesterol · Bifidobacterium · Gentle · SIBO-safe

Unlike inulin and FOS which commonly cause gas and bloating, acacia fibre ferments slowly and uniformly in the distal colon, producing steady short-chain fatty acid output without sudden gas accumulation.
