Can l-carnitine reduce post-COVID-19 fatigue?

A significant number of patients infected with the new coronavirus suffer from chronic fatigue syndrome after COVID-19, and their symptoms may persist for months after the infection. Nevertheless, no particular treatment for post-disease fatigue has been found. At the same time, many clinical trials have shown the effectiveness of l-carnitine in relieving fatigue caused by the treatment of diseases such as cancer, MS, and many other diseases. Therefore, it can be considered as a potential option to eliminate the effects of fatigue caused by COVID-19, and its consumption is recommended in future clinical trials to evaluate its effectiveness and safety. •The coronavirus disease is a viral infection that could induce different respiratory.•A significant number of patients infected with the new coronavirus suffer from chronic fatigue.•Clinical trials have shown the effectiveness of L-carnitine in relieving fatigue.
