Abstract

Vitamin A has been prescribed in many cases of immunodeficiency or infection, as researchers have found that vitamin A strengthens immunity and regulates immune cells such as neutrophils, macrophages and others. On the other hand, vitamin A treatment did not reduce the length of stay in the hospital or the death-rate sepsis patients. However, vitamin A plays a positive role in the treatment of COVID-19 through regulating many significant signaling pathways. In addition, it provides protection against measles and reduces mortality, and contributes in the treatment of tuberculosis through several mechanisms. In this review we aimed to explain the role of vitamin A in enhancing body immune functions and reducing inflammation in human body.
