The Beneficial Effect on the Bowel Function of a Food Supplement Based on Sea Buckthorn (Hippophae Rhamnoides L.) Extract in Subjects With Primary Functional Constipation

The study will aim to evaluate the efficacy and tolerability of a supplementation with Sea Buckthorn (Hippophae rhamnoides L.) at two different dosages for the management of the balance of intestinal function in subjects with primary functional constipation.

The primary outcome is the improvement of the frequency of bowel movements (SCBM) in subjects with functional constipation; then the secondary outcomes are the 1) improvement in stool consistency, assessed through the Bristol Stool Form Scale (BSFS) and 2) reduction in the typical symptoms of constipation, such as feeling of bloating and abdominal distension, feeling of heaviness, abdominal pain and flatulence, improving the quality of life of the subjects affected by primary functional constipation.
