Hi everybody,
I have been working on a thorough review on vitamin D supplementation--which I am finding much to my surprise to inhibit pretty much all parts of the immune system with a potency similar to that of corticosteroids--, and it would be very important to me, in order to finish this investigation and reach valid conclusions, to know the following questions. I'd really appreciate your inputs here! I will be sharing with you my article really soon:
For those of you who have been taking vitamin D for a long time:
1. How much of vit D3 (Cholecalciferol) have you been taking and for how long (more or less)?
2. If you are measuring blood levels, could you please let me know what concentration of 25-hidroxicolecalciferol (Calcifediol) and of 1,25-dihydroxycholecalciferol (calcitrol), in blood, have you achieved (please give me the units if possible)? I am much more interested in the levels of the active form, calcitrol, as I assume that its precursor, Calcifediol, did rise in serum by taking supplemental vit D3. I need to know if this makes the active vitamin D to increase even more (it is usually high in chronic diseases), given that this is the one that might be causing serious problems.
3. If you could let me know which were your previous levels of both vitamins (previous to start supplementing vit D3), this would be also really helpful!
Thank you very much in advance!
Sergio
