Xylooligosaccharides: Complete Guide to Benefits, Applications and Quality

2026-04-22

What are Xylooligosaccharides (XOS)?

Xylooligosaccharides (XOS) are prebiotic fibers composed of 2-10 xylose units linked together. Derived from plant sources such as corn cobs, sugarcane bagasse, and birch wood, XOS selectively feed beneficial gut bacteria, particularly Bifidobacteria, supporting digestive health and overall wellness. Research shows XOS is effective at very low daily doses, making it one of the most efficient prebiotics available.

Key Benefits

Gut Health: Selectively promotes the growth of beneficial Bifidobacteria, supporting a healthy gut microbiome and digestive function.
Immune Support: A healthy gut microbiome contributes to optimal immune function and the body's natural defense mechanisms.
Bone Health: May enhance mineral absorption, particularly calcium and magnesium, supporting bone density and strength.
Low Dose Effective: Effective at doses as low as 1-3g per day, making it one of the most efficient prebiotic fibers.
Blood Sugar Support: May help support healthy blood sugar levels and glucose metabolism through its effects on gut microbiota.
