topicCarnitine-Fatigue-Meta-Analysis
claimThe aim of the current study was to compare soluble blood biomarkers of ED and amino acid, fatty acid, carnitine, eicosanoid and resolvin related metabolism in a well-characterized cohort of individuals with or without PCS at a median of 37.4 weeks post-acute infection and to investigate whether these biomarkers are associated with PCS-related fatigue severity.

claim1 According to the World Health Organization (WHO), the post-COVID-19 syndrome (PCS) is a condition characterized by symptoms that persist for at least three months following infection with SARS-CoV-2, last for more than two additional months, and cannot be attributed to any other underlying disease.
