What is Vitamin D?
Vitamin D, often referred to as the "sunshine vitamin," is a fat-soluble vitamin crucial for maintaining several bodily functions. Unlike most vitamins, vitamin D can be synthesized by the body when skin is exposed to sunlight, specifically ultraviolet B (UVB) rays. This unique ability makes it more akin to a hormone, as it regulates various physiological processes.
There are two primary forms of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D2 is typically found in plant-based sources and fortified foods, while vitamin D3 is synthesized in the skin and found in animal-based foods. Both forms are converted into an active form, calcitriol, in the body, which is essential for calcium absorption, bone health, and immune function.
Vitamin D's role extends beyond bone health. It influences cell growth, neuromuscular function, inflammation reduction, and immune system modulation. Its deficiency is associated with various health issues, including osteoporosis, cardiovascular diseases, and autoimmune disorders.
