Ergocalciferol

Ergocalciferol, also known as vitamin D 2 and calciferol, is a type of vitamin D found in food and used as a dietary supplement.

In humans, the most important compounds in this group are vitamin D 3 (also known as cholecalciferol) and vitamin D 2 (ergocalciferol).

As a supplement it is used to prevent and treat vitamin D deficiency.

Since vitamin D 3 (also known as cholecalciferol) and vitamin D 2 (ergocalciferol) are fat-soluble, humans and other animals with a skeleton need to store some fat.

Ergocalciferol may be used as a vitamin D supplement, whereas cholecalciferol (vitamin D 3 ) is produced naturally by the skin when exposed to ultraviolet light.

There are conflicting reports concerning the relative effectiveness of cholecalciferol (D 3 ) versus ergocalciferol (D 2 ), with some studies suggesting less efficacy of D 2, and others showing no difference.

Food in which it is found include some mushrooms.

The US Department of Agriculture provided evidence that UV-exposed mushrooms contain substantial amounts of vitamin D. When exposed to ultraviolet (UV) light, even after harvesting, ergosterol in mushrooms is converted to vitamin D 2, a process now used intentionally to supply fresh vitamin D mushrooms for the functional food grocery market.

Ergocalciferol is a secosteroid formed by a photochemical bond breaking of a steroid, specifically, by the action of ultraviolet light on ergosterol, a form of provitamin D 2.

In human nutrition, ergosterol is a provitamin form of vitamin D 2 ; exposure to ultraviolet (UV) light causes a chemical reaction that produces vitamin D 2.

Ergocalciferol is a secosteroid formed by a photochemical bond breaking of a steroid, specifically, by the action of ultraviolet light on ergosterol, a form of provitamin D 2.

* Vitamin D forms such as ergocalciferol, cholecalciferol, and calcitriol

It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

Ergocalciferol and metabolites have lower affinity to the vitamin D-binding protein compared to the D 3 counterparts.

It is able to bind the various forms of vitamin D including ergocalciferol (vitamin D 2 ) and cholecalciferol (vitamin D 3 ), the 25-hydroxylated forms (calcifediol), and the active hormonal product, 1,25-dihydroxyvitamin D (calcitriol).

The binding affinity of ercalcitriol to the vitamin D receptor is similar to that of calcitriol.

Compared to other vitamin D compounds in clinical use (cholecalciferol, ergocalciferol), calcitriol has a higher risk of inducing hypercalcemia.

Like all mushrooms, shiitakes produce vitamin D2 upon exposure of their internal ergosterol to ultraviolet B (UVB) rays from sunlight or broadband UVB fluorescent tubes.

bisporus'' only contains 0.2 micrograms (8 IU) of vitamin D as ergocalciferol (vitamin D2), the ergocalciferol content increases substantially after exposure to UV light.

Ergocalciferol, also known as vitamin D 2 and calciferol, is a type of vitamin D found in food and used as a dietary supplement. Ergocalciferol may be used as a vitamin D supplement, whereas cholecalciferol (vitamin D 3 ) is produced naturally by the skin when exposed to ultraviolet light.

This includes vitamin D deficiency due to poor absorption by the intestines or liver disease.

It may also be used for low blood calcium due to hypoparathyroidism.

It may also be used for low blood calcium due to hypoparathyroidism.

It is used by mouth or injection into a muscle.

Excessive doses can result in increased urine production, high blood pressure, kidney stones, kidney failure, weakness, and constipation.

Excessive doses can result in increased urine production, high blood pressure, kidney stones, kidney failure, weakness, and constipation.

If high doses are taken for a long period of time, tissue calcification may occur.

Normal doses are safe in pregnancy.

It works by increasing the amount of calcium absorbed by the intestines and kidneys.

Ergocalciferol is available as a generic medication and over the counter.
