Safety and Efficacy of a Probiotic Supplement

Gastrointestinal Discomfort Clinical Trial

Official title: Safety and Efficacy of a Probiotic Supplement: Focus on Lessening Gastrointestinal Distress in Endurance Athletes

Status Completed

Clinical Trial Summary

Exercise-induced gastrointestinal dysfunction is common amongst endurance athletes and is characterized by gastrointestinal permeability, also known as "leaky gut." Probiotics have been shown to improve gut permeability through the secretion of mucin, immunoglobulin A and improvement in stability of tight junctions between epithelial cells. This study will determine the efficacy of a probiotic containing the bacterial strains P. acidilatici, CECT 7483, L. plantarum CECT 7484, L. plantarum CECT7485) in altering markers of gut inflammation and dysfunction, and symptoms of gastrointestinal distress.

Clinical Trial Description

This study is a randomized, placebo-controlled, double-blinded crossover study where trained runners that experience moderate gastrointestinal discomfort with exhaustive runs will be subjected to the probiotic intervention/placebo supplementation for one month with a one month washout period. The intervention consists of the probiotic strains Lactobacillus plantarum (CECT7484 and CECT7485) and Pediococcus acidilactici (CECT7483) at a ratio of 1:1:1 at a dose of 3b cfu/day. Probiotic/Placebo capsules will be taken once daily. Biological samples and symptom data collection will be collected at baseline and after one month of probiotic/placebo supplementation. Data are also collected after an in-house treadmill run after one month of supplementation. ;
