Beneficial Effects of a Food Supplement in Capsule Form and a Functional Chocolate Bar, Both Containing SYNBIO® Probiotic Strains and Grape Marc Plant Extract, on Healthy Adults.

The present clinical trial is a pilot open label, baseline-controlled (pre/post) experimental study, with a, a 2-week run-in period, 4-week intervention period and a further 2-week follow-up period without intervention to evaluate the potential prolonged effect of the functional products. Specifically, the supplementation should improve the parameters related to physical and mental well-being of subjects. Healthy adult participants were recruited and randomized into two treatment groups in a 1:1 ratio. Subjects will be randomly assigned to either the functional food or dietary supplement groups. The study will consist of three meetings at the coordinating center. The first visit will be for enrollment. Through an interview, the investigator will verify that the volunteer meets the inclusion criteria. The volunteer will receive an informed consent form to sign and the study protocol information sheet, which explains the study's progress in a simple and clear manner. The investigator will answer any questions and concerns the volunteer may have regarding the study. Subjects will be randomly assigned to either the functional food or dietary supplement group. Recruited subjects will be given questionnaires to complete independently. The second meeting will take place at the end of the month of taking the study products and will consist of the administration of the end-of-treatment questionnaires. The third and final meeting, two weeks after the end of treatment, will involve completing the questionnaires again to assess the possible persistence of the benefits that taking the products may have produced.
