What this panel measures
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.
How It Works
After purchase you will receive an email with your blood script along with instructions on where to complete the test. Results are typically emailed within 1–3 business days depending on the lab, followed by a follow-up call from Dr. Robinson with your dose plan and recommendations.
