What the Vitamin D Test Measures:

The Vitamin D test measures the level of total Vitamin D in your blood and is equivalent to 25-hydroxyvitamin D2 and D3 in plasma. It reflects your Vitamin D status over the past 1-2 months. As a part of a healthy lifestyle, a Vitamin D blood level in the 30-50 ng/mL range may help support metabolic, heart, brain and immune health.

Health Benefits Associated with an Optimal Vitamin D Level:

Vitamin D, like all nutrients, is essential for life. Our bodies need it from our environment (sunlight and food in this case) to function. It also plays an important role in building and maintaining strong bones. But that’s not all. Every cell in our body has receptors for vitamin D, meaning it can affect virtually everything that happens inside our cells. Research shows that people with higher blood levels of vitamin D live better for longer, with immune and cardiovascular systems that function better.
