What is d2 vitamin?

D2 vitamin, also known as ergocalciferol, is a type of vitamin D found in certain plants and fungi. It can also be produced by the body when the skin is exposed to sunlight.

D2 vitamin is essential for several bodily functions, including the absorption of calcium and phosphorus in the gut, maintaining healthy bones and teeth, and supporting the immune system.

D2 vitamin deficiency can lead to brittle bones, weak muscles, and an increased risk for infections. It can be found in fortified foods such as milk, cereals, and orange juice, as well as in dietary supplements and prescription medications.

However, D2 vitamin is not as well-absorbed or utilized by the body as another form of vitamin D called D3, which is found in animal products such as fatty fish, eggs, and liver. Therefore, many experts recommend getting vitamin D from a combination of sources, including sunlight, food, and supplements.
