Vitamin D Test

 

Vitamin D Deficiency

As much as 80% of the population in the United States is estimated to have low vitamin D levels. Emerging studies show that low vitamin D is associated with an increasing cause of death from ALL causes1. Low vitamin D is also associated with autoimmune diseases and overall immune health.

Recommended add-on test: 1,25 Vitamin D (active form)

Vitamin D Deficiency Causes

In a society that has almost every vitamin D type food available and abundant sunshine, many are left wondering, “Why are my vitamin D levels low”? The 7 most common causes for low vitamin D levels are:

  • Misuse/overuse of sunscreen
  • Diet high in processed foods
  • Inactivity
  • Stress
  • Smoking
  • Obesity
  • Thyroid issues

 

Why Get Your Vitamin D Levels Checked?

This test will allow you to supplement with the correct dosage of vitamin D. Since you can overdose on vitamin D, it is recommended to be tested once a season in order to adjust supplementation and maintain optimal vitamin D levels.

Vitamin D deficiency has been shown in studies to increase the risk of:

  • Autoimmune conditions like Multiple Sclerosis and Hashimoto’s
  • Type 1 Diabetes
  • Cardiovascular Disease
  • Increased blood pressure
  • Certain cancers

 

Vitamin D and Breast Cancer

Studies show a close correlation between optimal vitamin D and breast cancer. Many of these studies show that optimal vitamin D levels are associated with a 50% decrease in breast cancer risk2.
