Vitamin D3: The Sunshine Vitamin & Immune Modulator

• Mechanism of Action: Vitamin D3, cholecalciferol, is a fat-soluble vitamin that acts as a prohormone. Upon conversion to its active form, calcitriol, it binds to the vitamin D receptor (VDR) present in almost every cell in the body, including immune cells like macrophages, T cells, and B cells. This binding modulates gene expression, influencing a wide range of physiological processes, including immune function. Specifically, vitamin D3 promotes innate immunity by enhancing the production of antimicrobial peptides like cathelicidin and defensins, which directly kill pathogens. It also regulates adaptive immunity by influencing the differentiation and function of T helper cells, promoting Th1 responses for intracellular pathogens and suppressing excessive Th2 responses that can contribute to allergies. Furthermore, vitamin D3 helps maintain immune tolerance, preventing autoimmune reactions.

• Benefits for Immunity:
