Vitamin D2

Vitamin D2, also known as ergocalciferol, is a type of Vitamin D that is derived from plants and yeast. It is one of the two main forms of vitamin D, the other being cholecalciferol, which is derived from animals.

Sources

Vitamin D2 is produced by ultraviolet irradiation of ergosterol, a compound found in many types of fungi, including yeast. It can also be found in certain types of plants, such as alfalfa.

Function

Like other forms of vitamin D, vitamin D2 plays a crucial role in the body's absorption of calcium and phosphorus, which are essential for the development and maintenance of healthy bones and teeth. It also plays a role in immune system function.

Deficiency

A deficiency in vitamin D2 can lead to a condition known as rickets in children, which is characterized by soft, weak bones. In adults, vitamin D2 deficiency can lead to osteomalacia, a condition in which the bones become soft and weak due to poor mineralization.

Overdose

Excessive intake of vitamin D2 can lead to hypervitaminosis D, a potentially serious condition characterized by nausea, vomiting, loss of appetite, frequent urination, kidney stones, and bone pain.
