Exploring N-Acetylcysteine as a treatment for chronic fatigue syndrome

Official title: Mechanistic Assessment of N-Acetylcysteine as an Antioxidant Therapy for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Through Dose Response and Treatment Target Engagement

Funded at Weill Medical Coll of Cornell Univ · NIH-10821379 · Data updated 2026-11-12

This study is looking at whether a supplement called N-acetylcysteine (NAC) can help people with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) feel better by boosting a natural antioxidant in the body, and participants will either get NAC or a placebo to see how it affects their fatigue and overall health.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome who experience severe fatigue and related symptoms.

Less likely to help

Patients with other chronic illnesses or those not diagnosed with ME/CFS may not benefit from this research.

What this research studies

This research investigates the potential of N-acetylcysteine (NAC), a dietary supplement, as a treatment for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). The study aims to understand how NAC can help restore levels of glutathione, a key antioxidant in the body, which may alleviate symptoms of fatigue and improve overall health in patients with ME/CFS. Participants will receive either NAC or a placebo in a double-blind setup, allowing researchers to assess the effectiveness of NAC in reducing oxidative stress and improving symptoms. The research will also measure changes in brain chemistry and other biological markers to evaluate the treatment's impact.

Why it matters

Potential benefit: If successful, this research could provide a new therapeutic option for patients suffering from ME/CFS, potentially improving their quality of life.

How similar studies have gone: Preliminary findings from earlier studies suggest that NAC may effectively improve symptoms in ME/CFS patients, indicating a promising avenue for further exploration.
