Summary
This study tests whether three natural supplements—curcumin (from turmeric), resveratrol (from grapes), and stinging nettle—can improve physical and mental health in veterans with Gulf War Illness. 390 veterans from across the U.S. take part from home, reporting their symptoms online. The goal is to find a simple, low-cost way to ease this chronic condition.
