Polydextrose

Polydextrose is a synthetic polymer of glucose, produced by the condensation of dextrose (glucose) with sorbitol and citric acid. It appears as a white, water-soluble powder and is classified as a soluble dietary fibre by European regulatory authorities. Due to its low digestibility, polydextrose largely passes through the intestinal tract without being absorbed, resulting in a very low caloric contribution. It contributes to feeding the intestinal microbiota by acting as a fermentable substrate, thereby supporting normal bowel transit. In food supplements, polydextrose is primarily used as a bulking agent to adjust the volume of capsules without altering the activity of the active ingredients. Its tolerability profile is well established, and its use is regulated under European food legislation as a food additive (E1200).
