Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol.
Vitamin D is synthesized by the skin when weâre exposed to sunlight during certain times of the day and year, and can also be found in a limited number of natural and fortified foods sources. Vitamin D aids in the absorption of calcium, and vitamin D is essential for bone, teeth, muscle and immune system health.
