The body uses vitamin D to regulate levels of calcium & phosphate, the nutrients which protect & nourish the bones, teeth, & muscles. Vitamin D is crucial for maintaining healthy bones & the efficient metabolism of glucose. Most of the body’s vitamin D comes from sunshine exposure in the warmer months, & thus vitamin D deficiencies are much more common during the winter. Vitamin D is also found in our diet in oily fish, red meat, eggs, & some fortified products.
When should I get tested?

Your doctor may also require you to undergo regular blood testing when taking vitamin D supplements or other medications.
