Re: some blood test results

 ah yes
the main reason why I'm so deficient, besides the fact that I don't like taking the sun, is that I'm italian but lately I have lived on and off for 10 years in scandinavia.

I'm surprised it takes so little sun to have enough vit.D, are you sure? I was told it was fairly crucial not to be much dressed. I ask because it seems that vit. D is endemic, and I think it wouldn't be so if it was enough to walk all dressed in the sun 15 min a day. But I could be wrong.,

The 15 minutes should be full body exposure.  But even at that this will not always guarantee enough active vitamin D.  On major problem is that the conversion of vitamin D in to its active form requires properly functioning liver and kidneys.  So people with liver or kidney issues are less likely to covert vitamin D to its required active form.
