Ergocalciferol is known as Vitamin D2.

Vitamin D2, also known as ergocalciferol, is a type of vitamin D that is synthesized by plants. It is commonly found in a variety of food sources, including certain types of mushrooms and fortified products such as milk, orange juice, and cereal. Vitamin D2 can also be obtained through dietary supplements.

Vitamin D2 is a precursor to the active form of vitamin D in the body. When exposed to ultraviolet B (UVB) radiation from the sun, vitamin D2 undergoes a chemical reaction in the skin to form vitamin D3, which is the active form of vitamin D. Vitamin D3 is then converted in the liver and kidneys to its biologically active form, known as calcitriol.

The main function of vitamin D in the body is to regulate calcium and phosphorus levels, which are essential for bone health. Vitamin D helps the body absorb calcium from the intestines and promotes its deposition in the bones, thus preventing conditions like rickets in children and osteoporosis in adults.

Vitamin D2 is often used in medical treatments for individuals with vitamin D deficiency or conditions that affect the absorption of vitamin D, such as certain gastrointestinal disorders. It is also prescribed to individuals who have limited sun exposure or are unable to obtain sufficient vitamin D through their diet.

Although both vitamin D2 and vitamin D3 can effectively raise blood levels of vitamin D, some studies suggest that vitamin D3 may be more effective at maintaining optimal vitamin D levels in the body. However, both forms of vitamin D are considered important for overall health and should be obtained through a balanced diet or supplementation.

In conclusion, ergocalciferol, or vitamin D2, is a type of vitamin D that is synthesized by plants and can be obtained through certain food sources and supplements. It plays a crucial role in maintaining bone health and regulating calcium and phosphorus levels in the body.

Ergocalciferol, also known as vitamin D₂ and calciferol, is a type of vitamin D found in food and used as a dietary supplement. As a supplement, it is used to prevent and treat vitamin D deficiency. This includes vitamin D deficiency due to poor absorption by the intestines or liver disease.
