What Is the
Vitamin D3 Test All About?

The at-home Vitamin D3 lab test is an easy-to-do test that helps to discover & optimize the Vitamin D levels in your body. The test score shows your level of Vitamin D3 and allows you to optimize your levels.

If your Vitamin D levels are low enough to be considered a deficiency, you may experience a wide range of symptoms that include:

Now maybe you’re curious about me? Let me introduce myself…



I developed my passion for health & wellness after going through severe health complications at the age of 17.

I saw over 50 different doctors, tried over 100 different treatment protocols, but still saw no hope of recovery.

It wasn’t until I met an “alternative” health doctor whom explained to me how I got here and how I could become well again that I began the recovery process.

It was at this young age that I knew my life would be dedicated to helping others rebalance their bodies and renew their health.

Now, I have seen and overseen over 250,000 private client appointments through my Global Functional Medicine practice called EquiLife where we ship at-home lab tests, supplements, and wellness protocols to people all over the world. I strive to provide daily, free health education with my top ranking podcast and international best selling book, the “Rain Barrel Effect”.

Your Privacy Matters

When you purchase an at-home lab from EquiLife® your results are NEVER shared with your health insurance, life insurance, pharmaceutical companies, your PCP, or anyone else beyond the processing lab, our team, and you.

We take privacy very seriously and that’s why I am also trying to provide an opportunity to run this lab outside of the typical data-sharing world of conventional medicine.

We are a family oriented practice and our 50+ team members not only use these at-home labs with their wellness clients, but also with their own families.

Plus, we only use world-class labs that take as much pride in helping people take back control of their health as we do.
