Vitamin D deficiency is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D in the blood, which is the most accurate measure of stores of vitamin D in the body. [ 1][ 7][ 2] One nanogram per millilitre ( 1 ng/mL) is equivalent to 2.5 nanomoles per litre ( 2.5 nmol/L ). Severe deficiency: < 12 ng/mL = < 30 nmol/L[ 2 ...
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and for many other biological effects. [ 1][ 2] In humans, the most important compounds in this group are vitamin D 3 ( cholecalciferol) and vitamin D 2 ( ergocalciferol ). [ 2][ 3] The major natural source of ...

Vitamin D toxicity. Cholecalciferol (shown above) and ergocalciferol are the two major forms of vitamin D. Specialty. Endocrinology, toxicology. Vitamin D toxicity, or hypervitaminosis D, is the toxic state of an excess of vitamin D. The normal range for blood concentration in adults is 20 to 50 nanograms per milliliter (ng/mL).
One common active form is 1,25-dihydroxyvitamin D. [4] The term vitamin D in this article means cholecalciferol, ergocalciferol, 25-hydroxyvitamin D, and the active forms. The role of vitamin D is best characterized as enabling calcium absorption and regulating calcium homeostasis. Vitamin D also play a role in phosphate absorption. [5]
Calcitriol. Calcitriol is the active form of vitamin D, normally made in the kidney. [ 8][ 9][ 10] It is also known as 1,25-dihydroxycholecalciferol. It is a hormone which binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. [ 11]
Cholecalciferol is a form of vitamin D which is naturally synthesized in skin and functions as a pro-hormone, being converted to calcitriol. This is important for maintaining calcium levels and promoting bone health and development. [ 4] As a medication, cholecalciferol may be taken as a dietary supplement to prevent or to treat vitamin D ...
