Polydextrose
Polydextrose
Snapshot
Polydextrose is a synthetic soluble fiber used as a bulking agent and prebiotic to support digestive health, glycemic control, and satiety.
ย
What is Polydextrose?
Polydextrose is a random glucose polymer formed by the polymerization of glucose, sorbitol, and citric acid, yielding a highly branched, nonโdigestible fiber-like carbohydrate.
Where It Comes From
Manufactured through the catalytic condensation of glucose and sorbitol with a small amount of citric acid under heat, then neutralized, purified, and sprayโdried into a white, odorless powder.
Key Nutrients & Compounds
Provides approximately 70% dietary fiber by weight; low caloric value (~1โฏkcal/g); resistant to digestion in the small intestine and partially fermented by colonic bacteria into shortโchain fatty acids.
Health Benefits
Polydextrose supports bowel regularity by increasing stool bulk; acts as a prebiotic to nourish beneficial gut microbiota; moderates postโprandial blood glucose; and enhances feelings of fullness to aid weight management.
Recommended Dosage
4โ12โฏg daily, divided into two servings; begin at lower doses (2โ4โฏg) and increase gradually to minimize gastrointestinal discomfort.
How to Use It
Stir into water, beverages, or foods; incorporate into baked goods, yogurts, or meal replacements; always mix thoroughly and consume with adequate fluids.
Who Should Use It?
Individuals seeking to increase soluble fiber intake, improve digestive regularity, manage blood sugar responses, or enhance satiety without significant caloric load.
Possible Interactions or Cautions
Excessive intake can cause bloating, gas, or mild diarrhea; adjust dose according to tolerance; may alter absorption of certain nutrients if consumed in very high amountsโspace fiber and supplement intake.
Final Thoughts
Polydextrose is a versatile, lowโcalorie soluble fiber that supports gastrointestinal health, metabolic control, and satiety, making it a useful addition to functional foods and fiber supplements.
