Clinical Trial Summary

The goal of this clinical trial is to learn if supplementation with prebiotics and/or probiotics can lead to an improvement in symptoms of patients with functional constipation. The main objectives are:

• To evaluate the effect of the dietary supplements on the bowel frequency movements in patients with chronic functional constipation, after 8 weeks.

• To evaluate the stool consistency after 8 weeks (Bristol scale).

• To evaluate the quality of life scale score for patients with Constipation (CVE20 and GSRS scales), after 8 weeks.

Participants are randomized into the following groups:

• Group A: 20 assigned to probiotic + placebo

• Group B: 20 assigned to prebiotic + placebo

• Group C: 20 assigned to probiotic + prebiotic

• Group D: 20 assigned to the placebo + placebo

Participants took 4 units of product per day (2 of each assigned product) for 2 months.
