A Trial of a Multi-Component Nutritional Supplement in Hydrogen-Dominant Small Intestinal Bacterial Overgrowth

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 lactulose breath-test hydrogen/methane. Enrollment is single-arm with anticipated n = 10 (pilot) to establish feasibility/tolerability signals that inform future powered trials.
