Evidence supporting the use of: Vitamin A (retinol)
For the body system: Small Intestines
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Vitamin A (retinol) has a scientifically validated role in supporting the health and function of the small intestine, though the majority of research focuses on its general importance in maintaining mucosal integrity and immune defenses rather than direct treatment of small intestine-specific diseases. Vitamin A is essential for the maintenance and repair of epithelial tissues, including those lining the gastrointestinal tract. Deficiency in vitamin A can lead to impaired barrier function, making the small intestine more susceptible to infections and reducing nutrient absorption efficiency. Studies in both humans and animal models have shown that vitamin A deficiency results in morphological changes to the small intestine, such as villous atrophy and reduced goblet cell numbers, which can compromise digestive and absorptive functions. Additionally, vitamin A plays a key role in modulating immune responses in the gut-associated lymphoid tissue, supporting the body’s defense against enteric pathogens. While supplementation with vitamin A has not been widely studied as a specific therapy for small intestine diseases outside of deficiency states, its foundational role in maintaining intestinal structure and immune competence is well established. Therefore, its use for supporting general small intestine health is scientifically justified, though evidence is stronger for prevention and correction of deficiency rather than active treatment of specific small intestine disorders.
