Polydextrose is made up of sugars linked in chains. It is made in laboratories. People use these sugar chains in food and as medicine.

Polydextrose is taken by mouth for scaly, itchy skin (eczema), diabetes, impaired glucose tolerance (prediabetes), infant development, and as a prebiotic.

In foods, polydextrose is used as a sweetener and to improve the texture of foods.

How it works

Polydextrose passes undigested into the colon where it can increase bowel mass and possibly promote growth of certain bacteria that are thought to be beneficial.


Possibly Ineffective
Infant development

Research shows that adding polydextrose along with other prebiotics to infant formula does not affect how quickly a healthy infant gains weight or increases in length.


Likely safe

Polydextrose is LIKELY SAFE when used as a food additive, provided a serving contains less than 15 grams of polydextrose

Possibly safe

Polydextrose is POSSIBLY SAFE when taken by mouth in doses of less than 50 grams per day. Polydextrose can cause intestinal gas (flatulence), bloating, stomach cramps, and diarrhea

Possibly unsafe

Polydextrose is POSSIBLY UNSAFE when taken by mouth in single doses of more than 50 grams or in daily doses of more than 90 grams. High doses of polydextrose might cause severe diarrhea.
