Just got back my D3 levels and have a question, which I think I've asked before, but was just wondering....
Is there any significance to 1, 25 levels? My doc checked both 25-D, and 1, 25.
My 25-D was at 36. My 1, 25 was at 70. Both within normal ranges, although the 1, 25 was on the high side of things.
I believe 1,25 is basically 'storage levels' and can vary a lot, depending on infections, parathyroid and stuff like that?
My endo and almost every doc I've seen, considers 1,25 sort of useless, unless it's way out of range. So I was wondering if there is any significance to it at all.
Also wondering how much D3 most need to take to get into the 35-40 range. I've been taking 2500 IU/6 days a week, to get a serum of 36. I probably should get outside a bit more, I expect.
