Vitamin D is both a nutrient you eat as well as a hormone that's produced by your skin in response to sunlight exposure. It plays a significant role in bone health by helping regulate calcium and phosphorus, which are essential minerals that work together to build strong bones. Vitamin D also has a role in your nerve, muscle and immune systems, as well as your mental health.
This vitamin D blood test evaluates 25-hydroxyvitamin D (25-D): the best measure of how much vitamin D is stored in your body. A prolonged deficiency in vitamin D has been shown to lead to fatigue, bone pain and even depression.
