Vitamin D deficiency has a lot to do with your climate. It's not realistic to get all of your vitamin D from food no matter what. I'm guessing you live in Seattle or some other place where you forget what the sun looks like sometimes?

Is there any easy way to know if you suffer vitamin D defeciency? I'm in Vancouver, and especially at this time of year you end up inside for pretty much all the daylight hours Monday-Friday.

It's diagnosed through a blood test. As far as I know, you can't really diagnose it accurately in any other way. But in developed countries the rule of thumb on that is:

Do you work outside in the sun? Do you eat a lot of fish? Do you take a vitamin D supplement? If you answered "no" to all of these questions then you probably have a vitamin D deficiency. Vitamin D deficiency is very common.

>The National Health and Nutrition Examination Survey 2005 to 2006 data were analyzed for vitamin D levels in adult participants (N = 4495). Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D concentrations ≤20 ng/mL (50 nmol/L). The overall prevalence rate of vitamin D deficiency was 41.6%, with the highest rate seen in blacks (82.1%), followed by Hispanics (69.2%).

Looks as though I should probably be making a doctor's appointment...

I live in Kansas. I just don't go outside ever. I was always told I was at high risk of melanoma due to my mother having it so I learned to stay indoors. I start burning within 15 minutes of peak sun.

I'm not a doctor, and I'm sure you've gotten good information. But you don't need that much sun to get your vitamin D. 15 minutes is enough for a whole week.

I've found for me personally that vitamin D supplementation helps, but my tendons/muscle attachments are still weak and injury prone unless I get some real sun.
