摘 要：Vitamin D is a naturally occurring fat-soluble biologically inert hormone precursor that exists in two primary forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Its main biologic function is to maintain calcium and phosphorus concentrations as they are essential for overall bone health. It has a number of other physiological roles, including retaining muscle strength, moderating immune function, regulating cellular differentiation, and reducing inflammation. The major source of vitamin D for humans is the sun. Vitamin D3 can be synthesized in the skin upon exposure to sunlight, and thus sun exposure accounts for 80-90 percent of the vitamin D for most people. Vitamin D can also be obtained from the diet in the form of either vitamin D2 or vitamin D3. Vitamin D deficiency affects almost 50 percent of the population worldwide. An estimated 1 billion people worldwide, across all civilizations and age groups, have vitamin D deficiency. Vitamin D testing is a process of measuring the levels of vitamin D in the blood of a human.
