About this supplement

Polydextrose syrup/liquid is a water-soluble, low-calorie, low-viscosity dietary fiber derived from glucose, sorbitol, and citric acid. It is a randomly bonded polysaccharide of glucose with sorbitol end-caps and citric acid residues, creating a complex polymer resistant to mammalian digestive enzymes. This form is specifically a viscous syrup or liquid concentrate, making it suitable for incorporation into beverages, liquid supplements, and other aqueous formulations where powder dissolution might be problematic. It functions as a prebiotic fiber, promoting the growth of beneficial gut bacteria, and contributes to bowel regularity without significant caloric contribution.

Physical properties

Clear to pale yellow viscous syrup or liquid. Highly water-soluble. Typically 70-75% solids content. Mild, slightly sweet taste. Low viscosity relative to other syrups. Hygroscopic. Stable under acidic conditions and high temperatures.

How it’s made

Produced by vacuum melt polycondensation of glucose (dextrose), with sorbitol added as a plasticizer and citric acid as a catalyst. The reaction involves random polymerization, creating a complex, branched polysaccharide with glycosidic bonds (primarily 1,6- but also 1,2-, 1,3-, 1,4-) that are resistant to human digestive enzymes. The resulting polymer is then purified, dissolved, and concentrated into a syrup/liquid form.
