This review examines whether a natural supplement called acetylcarnitine might help treat long COVID symptoms like fatigue, brain fog, and depression. Acetylcarnitine is a substance your body normally makes that helps cells produce energy. The authors looked at research showing this supplement has helped some people with similar illnesses like ME/CFS and depression, and they propose studying whether it could help long COVID patients too.
This review is important because it identifies potential shared biological mechanisms between long COVID and ME/CFS—particularly mitochondrial dysfunction and energy metabolism—and proposes a specific, testable intervention. For ME/CFS patients, this work validates the overlap between these conditions and suggests that treatments showing promise in ME/CFS warrant investigation in long COVID populations.
This review does not prove that acetylcarnitine is an effective treatment for long COVID or ME/CFS; it synthesizes existing evidence and proposes a rationale for future studies. It does not establish causation between acetylcarnitine deficiency and symptom development, nor does it provide clinical trial data demonstrating safety and efficacy in these populations. The similarity of symptoms across long COVID, ME/CFS, and depression does not confirm they share identical underlying mechanisms.
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 →
