Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin A has a well-established role in supporting immune function and has been studied for its impact on infection, particularly in the context of deficiency. Vitamin A is essential for maintaining the integrity and function of epithelial tissues, which serve as barriers against pathogens. It is also crucial for the normal function of the immune system, including the development and differentiation of white blood cells such as lymphocytes. Clinical studies have shown that vitamin A supplementation can reduce morbidity and mortality from infectious diseases, especially in populations where deficiency is prevalent. For example, in children with measles or severe malnutrition, vitamin A supplementation has been shown to reduce the severity and complications of infection, and decrease mortality rates. The World Health Organization recommends vitamin A supplementation in children with measles in areas where deficiency is common. However, in well-nourished populations, routine supplementation for infection prevention is not generally supported by strong evidence. Most benefits are seen in deficient individuals. Overall, the use of vitamin A to support or treat infection is scientifically validated in certain contexts, primarily where deficiency or high risk of infection exists, and the evidence is moderate (rated 3/5) due to its context-dependent efficacy.
