In recent years, it has been suggested that nutritional deficiencies may be of causal relevance in individuals with ME/CFS. These include deficiencies of vitamins and trace elements. It is likely that the observed nutritional deficiencies contribute to the core symptoms of the disease.

All interventional trials in our ClinicalTrials.gov extract that list Coenzyme Q10 (CoQ10) as an intervention, across ME/CFS (2). 0 are currently open to enrolment and 2 have completed. Read the OSMF evidence profile for Coenzyme Q10 (CoQ10) for literature, mechanism and dosing context.
Intervention names are normalised from the registry's own arm labels, so the same compound can appear under a brand name, a generic name or a combination; check the full agent index for related entries.

How do I join a clinical trial?
Open the trial's ClinicalTrials.gov record (the "View on ClinicalTrials.gov" button), read the Eligibility Criteria and Contacts and Locations sections, and contact the study team listed there. Trials only enrol at the sites shown in the record, so check whether a site is near you or whether the study is remote/decentralised. Your own clinician can help you judge whether a trial is a sensible option and may need to provide medical records.
What do the trial phases mean?
Early Phase 1 / Phase 1 studies test safety and dosing in a small group. Phase 2 studies look for a signal of benefit in a larger group and keep checking safety. Phase 3 studies are large confirmatory trials designed to show whether a treatment works well enough for approval. Phase 4 studies follow approved treatments after they reach the market. "Phase not applicable" is used by the registry for behavioural, device, rehabilitation and other non-drug interventions.
Does the Open Source Medicine Foundation run these trials?
No. OSMF does not sponsor, run or recruit for any trial on this page. We compile public registry entries from ClinicalTrials.gov so patients and clinicians can find them in one place. For questions about a specific study, contact the sponsor or study team listed on its ClinicalTrials.gov record.
We summarise newly registered post-viral trials and notable results on the OSMF Substack.
