What is XOS and how does it work?

XOS is xylooligosaccharide, a prebiotic fiber that feeds beneficial bacteria in the gut. It supports digestion rather than adding live cultures like a probiotic.

How does it compare with a probiotic?

A probiotic adds live bacteria; this product feeds the bacteria already in your gut. Some people take both together for a synbiotic effect.

Can it cause gas or bloating?

Prebiotic fibers can cause mild gas when you start. Beginning with a smaller amount and building up usually reduces this.

Is it suitable for vegans and gluten-free diets?

Yes. The capsules are vegetable-based, and the formula is gluten-free, non-GMO and free of common allergens.

Does it contain sugar or sweeteners?

No. It is sugar-free and contains no artificial sweeteners.

How should I take it?

Take one serving of 1400 mg daily, ideally with water. Follow the label directions and check with a doctor if you take medication.

Our take on the Best Naturals Prebiotics Fiber XOS 1400mg

Best Naturals Prebiotics Fiber XOS delivers 1400 mg of xylooligosaccharide (XOS) per serving in vegan capsules. XOS is a prebiotic fiber that feeds beneficial gut bacteria rather than adding live cultures, so it works alongside a probiotic. The formula is gluten-free, non-GMO, sugar-free and free of common allergens, which suits adults with restrictive diets. It is a single-ingredient prebiotic, so it competes with blended prebiotic-probiotic products on simplicity rather than breadth.
