Probiotic (Visbiome) for Gulf War Illness
The overall objective is to determine whether Visbiome will improve
- intestinal symptoms of Irritable Bowel Syndrome (IBS) and
- non-intestinal symptoms (fatigue, joint pain, insomnia, general stiffness and headache) associated with IBS. All of these symptoms are part of the Gulf War (GW) illness.

Detailed Description
Specific Aims:
Aim # 1: Determine the efficacy of Visbiome on IBS symptoms in GW veterans.
Hypothesis: Treatment with Visbiome compared to placebo will improve global and individual symptoms of IBS
Aim #2 Determine the efficacy Visbiome in reducing non-intestinal symptoms of IBS (fatigue, joint pain, insomnia, general stiffness and headache).
Hypothesis: Treatment with Visbiome compared to placebo will improve non-intestinal symptoms of IBS in GW veterans.
Aim #3 Determine whether changes in gut flora and plasma cytokines correlate with treatment response in GW veterans
