ZRT Vitamin D Test Kit

$99.00

Get a clear and accurate picture of your Vitamin D status with this advanced at-home test.

Using highly precise LC-MS/MS technology, this test measures both Vitamin D₂ and Vitamin D₃ independently, offering a more complete and reliable assessment than standard testing.

Vitamin D plays a vital role in bone health, immune function, mood regulation, and cardiovascular support. When levels are low or imbalanced, it can contribute to fatigue, weakened immunity, hormone disruption, and long-term health challenges.

Designed for at-home convenience with clinical-level accuracy, this test provides the insight needed to support targeted supplementation and lifestyle choices for optimal health.

Once your results are in, you can schedule a Functional Lab Review where we’ll go through your results together and create a personalized plan to restore and maintain balance.

This is where we move from guessing to understanding.

NOTE: NOT AVAILABLE IN NY, CA, and MD

VITAMIN D

Many are unaware that vitamin D is not officially a vitamin – but actually a prohormone. In fact, we make most of our vitamin D when our skin is exposed to sunlight.

Statistics show a third of Americans have insufficient levels of vitamin D, with a leading cause being lack of sun exposure. This is common in northern climates where people don’t spend as much time outdoors, but studies indicate that even people in sunnier regions are often deficient due to concerns about the ill effects of too much sun.

Why the Concern About Low Vitamin D?

Vitamin D is important because it has a complex regulatory effect upon calcium in our bodies and in the mineralization of our bones. But that’s only skimming the surface of its function. Additional research shows vitamin D can play a protective role against certain cancers, development of diabetes and heart disease.

Vitamin D deficiencies are associated with hyperinsulinemia and belly fat, as well as contributing to psoriasis and acne. Additionally, sufficient levels of vitamin D, estrogen and testosterone are important for maintaining bone health in the perimenopause-menopause years.
