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 a fat-soluble nutrient that your body can make through your skinâs exposure to the ultraviolet B rays of the sun. Vitamin D is also acquired through fortified milk and oily fish such as salmon in the diet. Vitamin D is essential for bone growth and health and works to regulate the level of calcium in your body.
