Xylo-Oligosaccharides (XOS) is a natural prebiotic and water-soluble dietary fiber, typically derived from hydrolyzing xylan-rich plant materials (e.g., corn cobs, sugarcane bagasse), widely used in food & beverage (yogurt, low-sugar drinks, breakfast cereals), dietary supplements, and functional food formulations.

It stands out as a high-efficiency gut health booster: it resists digestion in the upper gastrointestinal tract, selectively nourishing beneficial bacteria (e.g., Bifidobacteria, Lactobacilli) with lower dosage needs than other prebiotics (e.g., FOS), while easing digestive discomfort like bloating. With ultra-low calories (≈0.2-0.4 kcal/g) and a very low glycemic index (GI <5), it acts as a mild sweetener without spiking blood sugar.
