Best Naturals Prebiotics Fiber XOS delivers 1400 mg of xylooligosaccharide per serving in a vegan capsule. XOS is a prebiotic fiber that feeds beneficial gut bacteria rather than adding bulk like psyllium or inulin. The formula is gluten-free, non-GMO and free of sugar, sodium and common allergens, which suits people who want a clean-label prebiotic. It is a single-ingredient option, so it lacks the fiber blends and digestive enzymes some competing prebiotics include.
