Evidence supporting the use of: Vitamin A (retinyl acetate)
For the body system: Mucus Membranes
Synopsis
Source of validity: Scientific
Rating (out of 5): 4
Vitamin A (retinyl acetate) is scientifically validated as essential for the health and function of mucus membranes throughout the body. Mucus membranes line many internal surfaces, including the respiratory, gastrointestinal, and genitourinary tracts, where they serve as critical barriers against pathogens and environmental insults. Vitamin A is a fat-soluble vitamin that is crucial for maintaining the integrity and differentiation of epithelial tissues, which include mucus membranes. Deficiency in vitamin A can lead to keratinization and breakdown of these tissues, resulting in symptoms such as dry eyes (xerophthalmia), increased susceptibility to infections, and impaired barrier function.
Numerous studies and reviews, such as those summarized by the World Health Organization and in peer-reviewed journals, demonstrate that vitamin A supplementation can restore normal structure and function to mucus membranes in individuals with deficiency. The molecular mechanism involves vitamin A’s active metabolite, retinoic acid, which regulates gene expression in epithelial cells, promoting their growth, differentiation, and mucus production. While direct studies on vitamin A supplementation in individuals with already sufficient levels are limited, the foundational role of vitamin A in mucus membrane health is well established. Therefore, its use to support mucus membranes is justified by strong scientific evidence, particularly in populations at risk of deficiency.
