Vit D or D3 ?

[sorte]

I saw some advises about using Vit D, which form is better D or D3 ? What dosage for kg's of the body ?

[stef2011]

No idea what are my calcium levels, but I used to eat diaries almost every day, kefir, jogurt, all types of cheese, everything except pure milk, last days I cut it a lot.

i asked about calcium rich foods because they might be those making pth low but it is best that it is vit d to make it low

So 5000 IU for 2 months and than test ?
yes

Btw, what is the reason exactly to cut calcium rich foods ?
the reason is that increasing vit d will make pth even lower, so if you make vitd25oh 100ng/ml the pth might go undetectable, and this is not good

As I know from recent studies most people with hbv have lower vit d than average.
So high vit D should make some impact on HBV DNA ? Are there any studies or we are just testing this.

So high vit D should make some impact on HBV DNA ?

not only high vit d levels but vit d levels reaching receptors in the tissues, these VDR receptors are blocked so you have to check intact pth to have confirmed the receptors are working (most viruses block vdr, hiv complitely shut down vdr activity for example)

It's quite complex as I see, but I like to learn. So how to confirm by PTH that VDR receptors are working ? It should go low ?

[stef2011]

yes because vitd25oh suppresses pth, no way it cannot suppress pth unless the receptors are blocked

I don't get it, so vit D may help to unlock them a bit ?
