What this Trial Is About
Researchers are studying gut and digestive health by evaluating changes before and after using a dietary supplement system for eight weeks. This study focuses on adults aged 18 to 80 years who have self-reported gastrointestinal symptoms. The goal is to understand how the supplement affects gut microbiota, inflammation, immune activity, and digestive function, which are important for overall health and well-being. Participants will take a dietary supplement system consisting of two products, PhytoPower 1 and PhytoPower 2, daily for eight weeks. They will mix one stick pack of each product into 16 fluid ounces of water and drink it each morning, with or without food. The study is open-label and single-arm, meaning all participants receive the supplement while maintaining their usual diet and lifestyle. During the study, participants will provide stool samples at the beginning and end to measure various biomarkers related to gut microbial diversity, inflammation, immune activity, digestion, and intestinal barrier integrity. They will also complete questionnaires about gastrointestinal symptoms and digestive well-being at several points throughout the study. Safety and tolerability will be monitored by tracking adverse events and compliance, with the total participation lasting eight weeks.
