In the US alone, 70% of Americans have either deficient or suboptimal levels of vitamin D. This is a massive problem given vitamin D's impact on our health and its effects on our gene regulation and expression. Vitamin D also regulates calcium and supports the functioning of the immune system, making it one of the most important biological compounds in the body. 

In today’s episode of a new series I’m calling Know Your Numbers, I dive deep into vitamin D. I discuss why vitamin D deficiency is a problem, how conventional medicine misses the mark in measuring vitamin D levels, how Functional Medicine treats vitamin D deficiency, and much more.

You can test your vitamin D levels with Function Health, a company I co-founded. It has been a lifelong dream for me. Function is the first-ever membership that includes 100+ lab tests and personalized insights from globally renowned doctors based on your results. Join Function at FunctionHealth.com.
