Land affected or burdened by an easement is called a servient estate, while the land or person benefited by the easement is known as the dominant estate.. If the easement benefits a particular piece of land, it is said to be appurtenant to the land.
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-2 comes mainly from vegetables. Vitamin D is a fat-soluble vitamin, meaning that it is stored in your fat tissue and can be recruited when your body needs it. Therefore, if you have extremely low levels of body fat or have impaired fat absorption, your ability to absorb vitamin D may be compromised.
