vitamin d results question
 
my labs: vit. d 25-oh- D3- 23 and 25-oh D2 <4.

I understand the difference between them- but what is the significance of having such a low amount. (especially the D2). I know that i need supplement, but wondering why the D2 is so low. How are these tests evaluated by the doc. and/or they both used? I am going to the doc next week but wonder if anyone knows. I have been googling but not finding the answers
thanks in advance

What is happening with D research is that D2 is now considered a waste of time and effort:

Quote:
Serum 25(OH)D levels are obtained when the disorder is suspected. Serum 1,25(OH)2D3 levels have no place in diagnosing the syndrome and will mislead the physician. Sunlight, artificial light, oral or parenteral vitamin D, or a combination, aimed at restoring circulating levels of 25(OH)D between 50–80 ng/mL is the treatment of choice. Controlled sunlight is the safest form of vitamin D repletion. Vitamin D3 cholecalciferol is the preferred form of oral vitamin D.
Your 25OH level is low. Target is 50-60ng/ml. Doctors are testing for this but still are very poor when it comes to interpreting the results, and treating. D2 is the storage form and considered inferior now to D3 which is the form that is made in your skin during sun exposure. If your D3 is low, then obviously you are not storing any as D2. You should therefore supplement with the active form, D3. But doctors still push the inferior form D2 on RX (it is the only RX form BTW).

I'd follow the advice of doctors on the net.
