Brief Summary

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

The objective of the pilot study is to validate the clinical use of an innovative symbiotic in patients with chronic kidney disease (CKD) stage 3b-4 and in healthy subjects.

The study aims at evaluating the effects of a symbiotic, consisting of a mixture of probiotics (Lactobacilli and Bifidobacteria), prebiotics (fructooligosaccharides and inulin) and natural antioxidants (a mix of quercetin, resveratrol and proanthocyanidins), by achieving two objectives:

1. Reduction of the serum levels of microbiota-derived uremic toxins, involved in a variety of cardiovascular complications in CKD
2. Reduction of intestinal permeability, inflammatory markers and oxidative stress
