Vitamin D Test - Quest lab draw
It is estimated that Vitamin D deficiency affects over 2 billion people globally. This is a big deal because Vitamin D is a big deal.
But what is it exactly? Vitamin D is a fat-soluble vitamin but also an important neuro-steroid hormone responsible for many elements in brain development and behavior. It is vital to immunity and to other physiologic functions and also increases brain levels of glutathione, a powerful natural antioxidant that is your body’s most important tool for detoxifying and excreting heavy metals.
Vitamin D also helps us absorb the minerals calcium and phosphorous, playing a vital role in forming and maintaining strong bones and teeth, regulates normal immune system function, maintains heart and lung health, and combats depression.

WHAT'S TESTED:
This Vitamin D test measures the amount of 25-hydroxyvitamin D in your blood. Your body absorbs vitamin D when exposed to sunlight or consuming fortified foods - storing it in fat cells until needed for use. Your liver and kidneys convert this inactive vitamin D to 25-hydroxyvitamin D, the active form the body needs.
WHY TEST?
Vitamin D is essential for your brain, immune system, and overall health. It helps your body absorb calcium and phosphorus for strong bones and teeth, supports heart and lung health, boosts natural detox processes, and can even help combat depression.
Vitamin D deficiency can indicate bone disease, nutrition disorders or other metabolic complications.
