Clinical Trial to Evaluate the Ability of Multi-Strain Postbiotic to Impact Inflammation, Immune Components, Gastrointestinal Symptoms, Recovery, Anxiety, and Intestinal Permeability
Lindenwood University
Summary
This study will evaluate the effects of a multi-strain postbiotic supplement on markers of inflammation, immune function, gastrointestinal symptoms, psychological well-being, and intestinal permeability in healthy adults. The primary objective is to determine whether four weeks of postbiotic supplementation alters physiological and perceptual responses to a standardized bout of moderate-to-high intensity exercise compared with placebo. Approximately 50 healthy men and women aged 18 to 55 years will be enrolled in a randomized, double-blind, placebo-controlled, parallel-group clinical trial. Participants will be randomly assigned to receive either a multi-strain postbiotic supplement or a matched placebo for 28 days. At the end of the supplementation period, participants will complete a 45-minute treadmill exercise bout at 75% of their individually determined maximum heart rate. Blood samples will be collected to assess biomarkers of inflammation, immune activity, and recovery. Gastrointestinal symptoms, intestinal permeability, anxiety, and perceived recovery will be evaluated using validated questionnaires. This study is designed to determine whether postbiotic supplementation modulates physiological stress responses and subjective well-being following prolonged exercise in healthy adults.
Description
This study is designed to evaluate the effects of a multi-strain postbiotic supplement on physiological, gastrointestinal, and psychological responses to a standardized bout of aerobic exercise in healthy adults. Prolonged moderate-to-high intensity exercise is known to acutely increase inflammatory activity, alter immune function, disrupt gastrointestinal integrity, and influence perceptions of recovery and anxiety. Nutritional interventions that can modulate these responses may be beneficial for supporting health and resilience in physically active populations. Postbiotics, which consist of…
