This paper proposes that low vitamin D levels may contribute to ME/CFS by allowing harmful inflammatory processes to continue unchecked in the body. Vitamin D normally acts as a brake on inflammation, but only when levels are adequate. The authors suggest that fixing vitamin D deficiency through supplementation might help reduce fatigue and inflammation in ME/CFS, though they acknowledge this theory needs to be tested in actual clinical trials.
This hypothesis offers a testable biological mechanism connecting vitamin D status to ME/CFS pathophysiology and suggests a potentially accessible intervention. If substantiated, vitamin D supplementation could provide a low-risk therapeutic option for a subset of ME/CFS patients and might explain why some patients report symptom improvement with vitamin D repletion.
This is a theoretical opinion piece, not a clinical trial, so it provides no evidence that vitamin D supplementation actually reduces fatigue or inflammation in ME/CFS patients. It does not establish causation between low vitamin D and ME/CFS, nor does it prove that the proposed NF-κB mechanism is the primary driver of the disease. The hypothesis remains speculative and requires prospective randomized controlled trials to confirm.
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 →
