Vitamin D | Arthritis Information

 

My Vitamin D level is low and I have to go on 1600 IU daily, but I am wondering if you get the same value from the sun, thru glass, as you do outside.  Does anyone know?

Thanks~~~
GG - did they run all 4 D tests?  Some of us are "Vitamin D hypersensitive" and it's the ratios that will hurt us. 

Gee Pip, I am not sure if they ran the 4 D test's or not.  I will call Monday and find out.  I am very careful about burning as I have had several basil cell carcinoma's removed. 
Thanks Pip!
Let us know! Just curious....do you know what your level was?  Mine is always low too.   They started me out on 1,000 iu  daily and now I am up to 2,000.   My RD clinic has their own special kind that I have to buy there.  It is vit D-3 she says it is absorbed easier than regular vit D. I think blood levels fluctuate quite a bit, because my second test was lower than the first.  I am also african american and we tend to have low levels  (although I am very very fair complexed) because increase pigment decreases absorption from the sun. I think they only have done one kind of test on me. My levels have ranged from16 to 25.  The goal is to get it to 35.I do not know what my level was.  I will also find that out when I call about the 4 D test.  I will keep you posted.   Mine was low too.  RD put me on 50,000 IU a week. Dr. Mercola has a good video on his website about Vitamin D and the sun - you need to stay outside, w/o any sunscreen, until your skin turns light pink - then you've "made enough" of your own. Ah the great Vitamin D controversy. I was just watching this incredibly long lecture about Vitamin D on You Tube when I checked in here and saw this post.

Here's a 7 minute video on You Tube from some guy who explains in easy-to-understand layman's terms the OTHER scientific theory about Vitamin D. You decide! (And then tell me 'cause I'm still investigating...)
