Interventions

  • PhytoPower 1 and PhytoPower 2 — DIETARY_SUPPLEMENT
    The intervention consists of a dietary supplement system comprising two study products, PhytoPower 1 and PhytoPower 2. Participants will be instructed to mix one stick pack of PhytoPower 1 and one stick pack of PhytoPower 2 together in 16 fl. oz. of water and consume the prepared mixture once daily in the morning, with or without food, for a total duration of 8 weeks (56 days). Study products will be dispensed at the Baseline Visit and again at the Week 4 Visit in quantities sufficient to last until the next scheduled visit.

Study Details

This clinical research study is being conducted to evaluate gut and digestive health before and after the use of a dietary supplement system over an eight-week period. Gut and digestive health play an important role in overall health, including digestion, nutrient absorption, immune function, and metabolic balance. Changes in gut microbiota, inflammation, and intestinal barrier function may contribute to digestive symptoms such as bloating, discomfort, altered bowel habits, and reduced well-being. In this study, adult men and women with self-reported gastrointestinal symptoms will consume a dietary supplement system daily for eight weeks. The study will measure changes in gut and digestive health using objective stool-based laboratory biomarkers and validated symptom questionnaires. Stool samples will be collected at baseline and at the end of the study to evaluate markers related to microbial diversity, inflammation, immune activity, digestive function, and intestinal barrier integrity. Participants will also complete questionnaires throughout the study to assess gastrointestinal symptoms and subjective digestive health and well-being. The study will also monitor the safety and tolerability of the dietary supplement system during the study period.

Arms

  • Experimental: Dietary Supplement Group
    Participants in this single-arm study will receive a dietary supplement system consisting of two study products, PhytoPower 1 and PhytoPower 2, administered once daily for 8 weeks. Participants will be instructed to mix one stick pack of PhytoPower 1 and one stick pack of PhytoPower 2 into 16 fl. oz. of water and consume the prepared mixture every morning, with or without food. The study will evaluate changes in gut and digestive health parameters using stool-based biomarkers and validated gastrointestinal symptom questionnaires over the study period.
