: Constipation is among the most common health impairments in Western countries. This study aimed to determine the effect of the chicory-derived fermentable dietary fiber Orafti(®) Inulin on stool frequency in healthy subjects with constipation. The study was conducted according to recent guidance documents for investigating bowel function and used a randomized, double-blind, placebo-controlled, cross-over design with a 2-week wash-out phase. Each study period comprised arun-in phase followed by 4 weeks daily intake of 3 × 4g inulin or maltodextrin (placebo). Forty-four healthy volunteers with constipation documented stool frequency and consistency, gastrointestinal characteristics and quality of life. Consumption of Orafti(®) Inulin significantly increased stool frequency compared to placebo (median 4.0 [IQR 2.5-4.5] versus 3.0 [IQR 2.5-4.0] stools/week, p = 0.038). This was accompanied by a softening of stools and trend toward higher satisfaction versus placebo (p = 0.059). In conclusion, Orafti(®) Inulin was effective in volunteers with chronic constipation and significantly improved bowel function.
