The effects of Polydextrose on constipated patients

A 4-arm study compared the effects of 0, 4, 8 or 12g polydextrose per day, for 2 weeks, in 192 functionally constipated patients. Those who consumed 12g polydextrose per day saw a significant increase in stool frequency by more than 2 bowel movements per week, compared to placebo. Additionally, degree of straining was significantly decreased, and proportion of complete bowel movements significantly increased, after both 8 and 12g.
