DOES IT WORK?
Results vary. Gum arabic (acacia gum) is genuinely interesting. It's a soluble prebiotic fiber that feeds beneficial gut bacteria and has clinical evidence for improving digestive health. At therapeutic doses (10-30g), it does real work. In supplements, it's mostly an excipient, but it's a better-than-average one.
