Overview

Vitamin D is an essential vitamin that helps regulate calcium and phosphorus in the body. It also plays a role in maintaining proper bone structure.

There are different forms of vitamin D, including ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Vitamin D is found in fish, eggs, and fortified milk. It's also made in the skin when exposed to sunlight. During periods of sunlight, vitamin D is stored in fat and then released when sunlight is not available.

Vitamin D supplements are commonly used to treat and prevent vitamin D deficiency. People who don't get enough sun and people who are 65 years or older are especially at risk for deficiency. People also use vitamin D for weak and brittle bones, heart disease, asthma, hay fever, and many other conditions, but there's no good scientific evidence to support many of these uses. There is also no good evidence to support using vitamin D for COVID-19.
