The goal of this clinical trial is to learn if a probiotic product can lower symptoms in adults with histamine intolerance. Histamine intolerance can cause stomach and bowel problems as well as symptoms such as flushing, itching, headaches, and dizziness. The study will also learn how safe and well tolerated the probiotic is.
The main questions this study aims to answer are:
Does the probiotic lower digestive symptoms linked to histamine intolerance?
Does it lower other common symptoms, such as flushing, itching, headaches, or dizziness?
Researchers will compare the probiotic to a placebo. A placebo is a look-alike powder that contains no active bacteria. This will help determine whether the probiotic works better than no treatment.
Participants will:
Take either the probiotic or the placebo once a day for four weeks
Visit the study center for screening and two study visits
Answer symptom questionnaires
Provide blood samples and urine samples
The study is for adults with symptoms of histamine intolerance. Participation is voluntary, and participants can stop taking part at any time.
