The Impact of a Daily Dietary Supplement on Glycemic Control in Individuals With Overweight or Obesity

September 17, 2026 updated by: Landon Deru, University of South Alabama

This clinical trial will evaluate the efficacy of Metabolic Master Pack over a 90-day intervention period. Sixty adults will be randomized to receive either Metabolic Master Pack or placebo. Participants will wear continuous glucose monitors throughout the study, complete repeated blood collections, undergo DEXA body composition assessments, and complete dietary records. Results will provide high-quality evidence regarding the product's effects on glucose regulation and metabolic health.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants will enroll in this randomized, double-blind, placebo-controlled, parallel-group trial in which they will consume the assigned intervention daily, 15 minutes before their largest meal. Continuous glucose monitoring will be used to characterize glucose responses under real-world conditions. Repeated blood draws will quantify changes in metabolic hormones and inflammatory biomarkers during three distinct standardized meal tests. These tests will take place at baseline, 45 days, and 90 days of supplementation. DEXA scans and anthropometric measurements, such as waist circumfrance, will assess body composition changes. Dietary recalls will be collected to evaluate behavioral changes and dietary adherence. Activity monitors will be used to assess physical activity and sleep patterns.

STATISTICAL ANALYSIS PLAN

Primary Outcome:

Change in acute fasted glucose AUC at baseline, Day 45 and Day 90.

Primary Analysis:

Mixed-effects linear model with:

  • Fixed effects: group, time, group × time
  • Random effect: participant

Secondary Analyses:

  • Repeated-measures mixed models for hormones
  • Repeated-measures mixed models for body composition
  • ANCOVA models controlling for baseline values
  • Sensitivity analyses for dietary intake and adherence
  • Physical Activity data as a covariate with glucose data

Power Analysis:

Assuming an effect size of d=0.60, alpha=0.05, and 80% power, 52 participants are required. Enrollment of 60 participants allows for approximately 15% attrition.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
