Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Vitamin A is scientifically validated as important for the health of mucus membranes throughout the body. Mucus membranes line various passages—including the respiratory, digestive, and reproductive tracts—and act as barriers against pathogens. Vitamin A (especially as retinol and its derivatives) plays a critical role in maintaining the structure and function of epithelial cells, which make up these membranes. Deficiency in vitamin A is well-documented to lead to keratinization and drying of mucosal surfaces, increasing susceptibility to infections and other complications. Clinical and epidemiological studies demonstrate that adequate vitamin A intake helps preserve the integrity and protective functions of mucus membranes. The World Health Organization and various public health agencies recognize vitamin A as essential for normal mucosal and epithelial health. While most research focuses on deficiency states, the mechanistic understanding of vitamin A’s role in gene expression and cellular differentiation provides robust scientific support for its use to support the mucus membranes body system. However, it is important to note that supplementation is primarily beneficial in cases of deficiency, and excessive intake can be toxic.
