Fructo Oligosaccharide is a short-chain oligosaccharide composed of 3–10 fructose units that functions as a highly effective prebiotic ingredient. Its non-digestible structure allows it to reach the intestines intact, where it selectively nourishes beneficial bacteria such as Bifidobacteria.
Compared to traditional sweeteners and standard dietary fibers, Fructo Oligosaccharide offers both nutritional and functional advantages. Its prebiotic activity supports digestive wellness while maintaining low sweetness intensity and reduced caloric value. FOS also blends easily into powders, beverages, supplements, and skincare products without significantly affecting texture or formulation stability.
