Vitamin D is a group of structurally related, fat-soluble compounds responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, along with numerous other biological functions. [1] [2] In humans, the most important compounds within this group are vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol). [2] [3]
1α-Hydroxyvitamin D 5 is a chemical derivative of vitamin D 5.The motive to study 1α-hydroxyvitamin D 5 as a potential pharmaceutical drug stemmed from the tendency of calcitriol, a natural metabolite produced in the kidney, to cause toxic hypercalcemia in patients when dosed at concentrations needed to interrupt prostate cancer cells' cycle and stimulate apoptosis.
Units do not necessarily imply anything about molarity or mass. A few substances are below this main interval, e.g. thyroid stimulating hormone , being measured in m U/L, or above, like rheumatoid factor and CA19-9 , being measured in U/mL.
The recommended daily intake of vitamin D is 600 IU (international units) for most adults, increasing to 800 IU for those over 70. While an egg is often celebrated for its nutritional value, one ...
People who take vitamin D supplements before being admitted for intensive care are less likely to die than those who do not take vitamin D supplements. [49] Additionally, vitamin D levels decline during stays in intensive care. [50] Vitamin D 3 (cholecalciferol) or calcitriol given orally may reduce the mortality rate without significant ...
22-Dihydroergocalciferol is a form of vitamin D, also known as vitamin D 4. [2] It has the systematic name (5Z,7E)-(3S)-9,10-seco-5,7,10(19)-ergostatrien-3-ol. [1]
Multivitamins nutrition facts label showing that the international unit of, for example, vitamins D and E correspond to different gram values. In pharmacology, the international unit (IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances.
Vitamin D toxicity, or hypervitaminosis D, is the toxic state of an excess of vitamin D. The normal range for blood concentration of 25-hydroxyvitamin D in adults is 20 to 50 nanograms per milliliter (ng/mL).
