GrassrootsHealth Certified Vitamin D*practitioners


You don't know what you don't know .... and this is so ubiquitous when it comes to nutrition.

What are your Vitamin D levels? Think about the 21st Century western world - for almost all of human history, we were outside most of the time and in the sun.

For the last 50+ years, who is outside, during the middle of the day, with skin (not just face) exposed to the sun getting their minimum erythemal dose ("the amount of UV radiation that will produce minimal erythema (sunburn or redness caused by engorgement of capillaries) of an individual's skin within a few hours following exposure.")?

Very few of us! That is why Vitamin D deficiency is rampant!

And if you think you get enough Vitamin D from food - oh my! Highly doubtful.

Take a look at the Top 10 Vitamin D foods. The first one is Cod Liver Oil, not really a "food" most consume on a daily basis! The rest are fish with milk and yogurt rounding out the list. You would have to eat over 1 pound of these fish or drink/eat about 30 cups of milk or yogurt per day to get 4000 IU of Vitamin D! Yikes!

One of the most enlightening learning experiences for me has been to become a GrassrootsHealth Certified Vitamin D*practitioner (currently one of only four in Texas!).

Whether you already have been diagnosed with a chronic disease, are training for CrossFit or other sports, or just wish to stay healthy, take a look at the chart below and click here for the Vitamin D Dosing Calculator. Get started!

Importance of Vitamin D

"A Scientists’ Call to Action has been issued to alert the public to the importance to have vitamin D serum levels between 40 and 60 nanograms/ milliliter (100-150 nanomoles/liter) to prevent these diseases. Implementing this level is safe and inexpensive."

Blood levels vs. Intake

"... there is a wide range of individual serum levels at any given intake amount."

The Flu and Vitamin D

"D*action participants who had a 25(OH)D serum level >= 40 ng/ml (100 nmol/L) reported 50% fewer cases of the flu 16% fewer colds than those who had a serum level less than 20 ng/ml (50 nmol/L)."

Breast Cancer and Vitamin D

"25(OH)D Serum Levels >= 50 ng/ml Showed an 80% Reduction in Breast Cancer Incidence"
