DOES IT WORK?
Results vary. Gum acacia (also called gum arabic) is a soluble fiber from the Acacia senegal tree. It's used as a binder and emulsifier in supplements, but it's also a legit prebiotic fiber when dosed properly (5-30g). At typical supplement excipient amounts though, you're not getting enough for gut benefits.
