Synopsis

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

Vitamin A is scientifically recognized for its essential role in supporting the health and function of various glands within the endocrine (glandular) system, particularly the thyroid and adrenal glands. Vitamin A is required for the synthesis of thyroid hormones and helps regulate gene expression in endocrine tissues. Deficiency in vitamin A has been linked to altered thyroid gland metabolism and function, as well as impaired adrenal function. Furthermore, vitamin A is necessary for the normal development and maintenance of epithelial tissues, which include the linings of many glands.

Multiple animal and human studies have demonstrated that vitamin A deficiency can lead to thyroid gland enlargement (goiter), decreased synthesis of thyroid hormones, and increased susceptibility to infections affecting glandular tissues. Supplementation with vitamin A has been shown to improve thyroid function in populations at risk for deficiency. While vitamin A is not a specific treatment for glandular disorders in individuals with adequate nutritional status, its essential physiological role in endocrine health is well-established and scientifically validated.

However, it should be noted that excessive intake of vitamin A can be toxic and may harm glandular and other body systems. Therefore, vitamin A supplementation should only be used to address deficiency or maintain adequate intake, not as a cure-all for glandular issues. In summary, the use of vitamin A to support the glandular system is grounded in strong scientific evidence related to its role in endocrine function and health.
