Summary

This study tests whether taking oral glutamine, a dietary supplement, three times a day for 12 weeks can reduce chronic stomach pain, bloating, and diarrhea in veterans with Gulf War Illness. Researchers will also check if it helps repair the gut lining. The trial involves 80 veterans and compares glutamine to a placebo (whey protein).

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: oral glutamine (a dietary supplement)
What this could lead to: If it works, this could point toward a simple, safe supplement to relieve chronic gut problems in veterans with Gulf War Illness.
What could go wrong: This is a small, early-stage trial (80 people) testing a supplement, not a drug. Results may not apply to all veterans, and the benefit may be no better than placebo.
