Vitamin D2 | Community Health

Vitamin D2, also known as ergocalciferol, is a type of vitamin D found in certain foods, such as mushrooms, and is used as a dietary supplement to prevent and treat vitamin D deficiency. With a history dating back to 1936, vitamin D2 has been widely used to address issues related to poor absorption, liver disease, and hypoparathyroidism. According to the [[national-institutes-of-health|National Institutes of Health]], vitamin D2 is essential for maintaining strong bones, immune function, and overall health. However, excessive doses can lead to vitamin D toxicity, causing symptoms such as increased urine production, high blood pressure, and kidney stones. As of 2023, vitamin D2 was the 48th most commonly prescribed medication in the United States, with over 10 million prescriptions filled, as reported by the [[cdc|Centers for Disease Control and Prevention]]. With its rich history, diverse applications, and potential risks, vitamin D2 remains a crucial component of modern nutrition and healthcare, with ongoing research and development by organizations such as the [[mayo-clinic|Mayo Clinic]] and the [[who|World Health Organization]].
