An Open-Label Pilot Trial of a Multi-Component Nutritional Supplement in Hydrogen-Dominant Small Intestinal Bacterial Overgrowth
National University of Natural Medicine
Summary
The goal of this trial is to evaluate the safety and tolerability of an 8-week, multi-component nutritional supplement (AV1PD1A) in adults with hydrogen-dominant small intestinal bacterial overgrowth (SIBO). The main questions the study aims to answer are: 1. Is the product safe and well-tolerated over 8 weeks, as measured by bloodwork, vital signs, and adverse effects? 2. How many participants adhere to the intervention without a dose modification, hold, or discontinuation? Exploratory questions include: do GI symptoms and quality of life ratings improve, and do hydrogen/methane levels on lactulose breath testing change from baseline to week 8? There is no comparison group; this is a prospective, open-label, single-arm pilot trial (n=10). Participants will: * Be screened and confirmed to have hydrogen-dominant SIBO by lactulose breath test (with 24-hour prep diet and overnight fast). * Take AV1PD1A, three capsules daily for 8 weeks. * Attend three clinic visits at baseline, week 4, and week 8 for vital measurements, fasting blood draws, and adverse event checks. * Complete questionnaires on symptoms and quality of life. * Repeat the lactulose breath test at week 8 to assess changes in hydrogen and methane.
Description
Prospective, single-site, open-label, single-group pilot conducted at NUNM's Helfgott Research Institute (Portland, OR). The investigational product (AV1PD1A) is a multi-component dietary supplement containing Saccharomyces cerevisiae fermentate (EpiCor), N-acetyl-glucosamine, Saccharomyces boulardii, Lactobacillus rhamnosus (heat-killed), methylcobalamin, berberine, and gingerol (ginger extract). Dosing: 3 capsules daily for 8 weeks. Primary outcome is safety/tolerability (labs, vitals, AEs). Exploratory outcomes include validated PROMIS instruments, IBS Adequate Relief, and changes in lactul…
