Vitamin D¶

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.
