You live in sunny Arizona so why would you need testing to measure your vitamin D level?  Surprisingly, a great number of people living in sunny climates still have a vitamin D deficiency.  People that live in a climate like ours tend to to cover their skin more, apply a lot of sunscreen, and even avoid going outdoors altogether when it is too hot out. 

The darker your skin pigment, the longer you have to stay in the sun to obtain adequate vitamin D.  This, along with other factors such as thinning skin from ageing, spending greater amounts of time indoors, dietary choices, obesity, and pregnancy status can all contribute to low levels of vitamin D.  With so many different internal and external factors that contribute to your vitamin D level, it is important to get tested.

The unfortunate result of a deficiency could be any of the following:

  • poor cognitive function
  • frequent infections
  • painful and weak bones
  • increased risk of cancer


You also may have no symptoms at all, but this does not mean you do not have a vitamin D deficiency.  In any case, measuring your vitamin D is essential to improving your health.
