What this trial studies

This study aims to evaluate the effectiveness of a high-quality preparation of coenzyme Q10 (ubiquinone) in improving symptoms, functionality, and quality of life for veterans suffering from Gulf War illness. Participants will receive either the active supplement or a placebo in a randomized manner. The study will include veterans who meet specific deployment and symptom criteria and will involve remote participation for assessments. Blood draws will be conducted at local facilities to monitor health outcomes throughout the study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option to alleviate symptoms and improve the quality of life for veterans with Gulf War illness.

How similar studies have gone: Previous studies have indicated potential benefits of coenzyme Q10 in various conditions, but this specific application for Gulf War illness is being explored in this replication study.
