2023 Prospective Clinical Study

Effect, Tolerability, and Safety of Exclusive Palatable Elemental Diet in Patients with Intestinal Microbial Overgrowth

Our 2023 clinical trial of a 2 week course of mBIOTA in SIBO and IMO patients. The mBIOTA Elemental diet was tolerated by 100% of patients, eradicated overgrowth in 73% of patients overall and provided adequate relief from symptoms in 83% of patients.

Successful Outpatient Management of Partial Small Bowel Obstruction

A 2 week outpatient course of mBIOTA Elemental Diet successfully resolved symptoms and improved bowel dilation in a patient with a partial small bowel obstruction.

Reduction of Methane Levels Correlates with Fecal Abundance of M. smithii

An exclusive 2-week course of mBIOTA demonstrated a prolonged reduction in M. smithii levels for at least two weeks post-completion, which was associated with a corresponding decrease in breath methane levels in individuals with IMO.

Maintained Visceral and Total Body Fat Loss Following Elemental Diet

A 2 week exclusive course of mBIOTA leads to a significant reduction in body fat percentage and visceral fat area with a minimal drop in lean weight.

Achieving Organoleptic Acceptability with Elemental Formula

In this prospective, single-blind comparative study, mBIOTA was significantly more palatable than a conventional elemental diet and resulted in optimal patient compliance during a 2-week exclusive elemental diet therapy.

Compliance, Safety, and Effect of Exclusive Palatable Elemental Diet in Microbial Overgrowth

A 2-week mBIOTA elemental diet normalized breath tests in 73% of IMO/SIBO patients. The diet demonstrated a favorable safety profile and achieved the highest known compliance rate for an oral elemental diet.
