ABOUT INFOODS® IBS

inFoods® IBS is a diagnostic-guided therapy that identifies patient-specific food triggers responsible for symptoms such as abdominal pain, bloating, diarrhea, and constipation. Using a simple finger-stick blood sample, the test enables physicians to recommend targeted dietary changes tailored to the patient's immune response—offering a non-pharmaceutical, precision-based approach to symptom relief.

A multicenter, double-blinded sham-controlled trial on the inFoods® IBS test was published in the June 2025 issue of Gastroenterology, a peer-reviewed GI journal. The study demonstrated statistically significant outcomes:

59.6% of patients in the treatment group (who eliminated identified trigger foods) achieved the FDA's endpoint for abdominal pain reduction, compared to 42.1% in the control group.

Among IBS-C patients, 67.1% of patients in the treatment group vs. 35.8% in the control group.

Among IBS-M patients, 66% of patients in the treatment group vs. 29.5% in the control group.

These results highlight the potential effectiveness of a personalized dietary therapy based on inFoods® IBS in IBS patients. The study was conducted at leading U.S. institutions including Cleveland Clinic, Mayo Clinic, and University of Michigan.

ABOUT IRRITABLE BOWEL SYNDROME (IBS)

IBS affects an estimated 30 to 45 million adults in the United States, representing 10%–15% of the adult population. The condition leads to decreased quality of life, lost productivity, and reliance on medications with adverse side effects. Current IBS drugs address symptoms without targeting the underlying dietary triggers specific to each patient.

inFoods® IBS takes a fundamentally different approach—a precision diagnostic that identifies individual food triggers via a simple finger-stick blood test, enabling targeted, patient-specific dietary recommendations. This non-pharmacologic, personalized solution addresses a significant unmet clinical need within an estimated $30 billion total addressable market.
