Evidence supporting the use of: Vitamin A (mixed)
For the body system: Mucus Membranes
Synopsis
Source of validity: Scientific
Rating (out of 5): 5
Vitamin A (mixed, typically referring to a combination of retinol and carotenoids) is scientifically validated as essential for the health and maintenance of mucus membranes throughout the body. Mucus membranes line various tracts (respiratory, gastrointestinal, urinary, and reproductive tracts) and provide a protective barrier against pathogens and environmental irritants. Vitamin A is crucial for the differentiation and proper functioning of epithelial cells, which make up these membranes. Deficiency in vitamin A can result in keratinization and dryness of epithelial tissues, including the eyes (xerophthalmia), respiratory tract, and gastrointestinal lining, increasing susceptibility to infections and tissue damage.
Multiple clinical and epidemiological studies demonstrate that adequate vitamin A intake reduces the risk of infections by maintaining the integrity and function of mucus membranes. The World Health Organization recommends vitamin A supplementation in populations at risk of deficiency, primarily because of its role in supporting epithelial and immune health. Reviews published in journals such as The American Journal of Clinical Nutrition and Nutrition Reviews confirm vitamin A’s critical role in mucosal immunity and tissue maintenance. Thus, the use of vitamin A to support mucus membrane health is based on robust scientific evidence.
