Free Nutritional Advisor
Free Nutritional AdvisorVitamin D is an essential nutrient obtained through foods and dietary supplements, or produced in the skin following sun exposure. Vitamin D plays a significant role in bone strength, immune response, heart health, mood regulation, brain function, and metabolic processes. Optimizing vitamin D levels can help your body function at its best.
What it measures
This test accurately measures your levels of 25-hydroxyvitamin D, the active form of vitamin D that your body utilizes for various essential functions. 25-hydroxyvitamin D is the best indicator of your overall vitamin D status.
How often should you test?
A single test provides an accurate snapshot of your current vitamin D levels. But by repeating the test, you can track the effects of D3 supplementation on your body over time. We recommend retesting every 3 to 4 months to keep an eye on your progress.
