There are a range of influences on a person’s vitamin D status, such as lifestyle, age, and environment, which determine how much vitamin D may be appropriate.

While there are multiple ways to assess vitamin D levels, one widely used method is a 25‑hydroxyvitamin D test. It measures the 25(OH)D, also called calcidiol, in your blood. Vitamin D must go through several transformation processes before your body can use it, and calcidiol is the form that vitamin D is first converted into when it reaches the liver.
