This review looked at 60 research studies to see if vitamins and minerals might help reduce fatigue in people with conditions like ME/CFS. Most studies (50 out of 60) found that taking supplements like vitamin D, vitamin B, Coenzyme Q10, and L-carnitine did help people feel less tired. While these results are promising, more research is needed to know which supplements work best and for whom.
For ME/CFS patients, fatigue represents the core, disabling symptom that standard treatments rarely address effectively. This review summarizes evidence that specific micronutrients show promise in reducing fatigue across multiple chronic conditions, potentially offering a therapeutic avenue worth exploring in ME/CFS-specific trials. Understanding which nutrients have the most robust evidence may help guide both future research and informed discussions between patients and clinicians.
This review does not prove that any single nutrient will help an individual ME/CFS patient, as most included studies involved different conditions, dose regimens, and fatigue definitions. The finding that 50 of 60 studies showed benefit does not establish which nutrients are most effective for ME/CFS specifically, nor does it demonstrate optimal dosing, duration, or whether benefits persist long-term. Correlation between supplementation and fatigue improvement does not rule out placebo effects or other confounding variables.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
