| Number of participants | 26 |
| Population | Healthy adult volunteers |
| Intervention | Flax fiber supplementation (dietary flaxseed fiber) |
| Comparator | Psyllium fiber supplementation (comparison fiber intervention) |
| Duration | 2 weeks |
| Health claim | Linum usitatissimum (flax) may support bowel regularity and improve laxation through dietary fiber effects |
| Outcome measured | Fecal weight (stool bulk), laxation parameters, glycemic response, acceptability of fiber supplementation |
| Main result | Flax fiber supplementation increased fecal weight, demonstrating a stool-bulking effect. The results suggest that flax fiber can improve bowel function through increased stool bulk, although psyllium showed a stronger laxative effect. |
| Risk of bias | Moderate risk of bias: small sample size, short intervention period, healthy participants rather than patients with constipation |
| Funding | Not clearly reported in available abstract information |
