Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomised and controlled trial, in which the effect of a dietary supplement is evaluated for reduction of intestinal permeability levels of subjects with high levels of zonulin in feces

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Randomized clinical trial, with masking of the statistician and the evaluator, to assess the effect of a food supplement, composed of substances that promote intestinal mucosa repair, on the levels of zonulin in feces and consequently on intestinal permeability. A control group of subjects not receiving any type of supplementation will be used to compare the effectiveness of the treatment.

The main objective of this study is to determine if the use of a dietary supplement composed of glutamine, butyrate and lion's mane, among others, corrects the levels of zonulin in feces.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

It has been estimated to conduct a trial with subjects who are distributed in two groups: an intervention group of patients to whom supplementation is provided, and a control group of subjects who do not receive any type of supplementation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dietary supplement Group

Subjects belonging to the experimental group will be provided with the PermeaIntest supplement, which they will take for 60 days, 1 sachet in the morning and 1 sachet in the evening in half a glass of water. Subjects will have a stool sample collected before and after ingestion of the dietary supplement.
