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

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.

Inclusion Criteria:

• Subjects between 18 and 65 years of age with elevated levels of zonulin in stool (greater than 80 ng/ml).

Exclusion Criteria:

• Taking any type of antibiotic in the last month
• Taking prebiotics or probiotics products in the last month.
