What is the Origin of Vitamin D and Thyroid?

A recognized clinical relationship within endocrinology and nutritional science, highlighting the essential, non-classical, hormonal role of Vitamin D in systemic regulation and immune modulation. This connection is vital for comprehensive endocrine assessment and management of thyroid disorders.

What is the Mechanism of Vitamin D and Thyroid?

Vitamin D acts as a transcriptional regulator, binding to its nuclear receptor to influence the expression of genes involved in immune response and cellular proliferation within the thyroid gland. Deficiency is often associated with increased risk of thyroid autoimmunity and goiter, suggesting a key role in immune tolerance and the maintenance of thyroid cell integrity and function.

Vitamin D and Thyroid

Meaning

The established bidirectional relationship between the fat-soluble secosteroid Vitamin D, which acts as a pro-hormone, and the function of the thyroid gland, which is crucial for systemic metabolic regulation. Vitamin D receptors are widely present in thyroid cells, and adequate levels are essential for modulating thyroid hormone synthesis, preventing autoimmune thyroid conditions like Hashimoto’s thyroiditis, and regulating parathyroid hormone.
