Vitamin D Question

Maybe someone can give me some help here. I got my latest 
blood test results back and while the calcium levels remain 
very good at 9.2 ( range is 8.5 to 10.5 ), my Vitamin D 
level has me perplexed. It is 14 where the normal range is
10 to 68. I realize that it is in the Lo-normal range but i 
am wondering what happens to all the vitamin d in my system.

Am i excreting the excess? IS there any excess to excrete?
I  take a good multi=vitamin that includes 400 u.i of Vit D 
daily as well as another 400 u.i in my citrical tablets. I 
am also out in the sun - albeit a lot less with the onset of 
winter.

I will be seeing two endocrinologists as well as my other 
treating physicians in the next few weeks and i will let the 
group know what statements they give me.

Sincerely
