Re: Finally found a simply worded study explaining Vitamin 25D has no impact on

Concerning this qoute:

" Indeed, neither increased exposure to sunlight nor increased

oral intake of vitamin D raised blood concentrations of

1,25(OH)2D (59-61). "

Citation # 60 is this one:

Heaney RP, Davies KM, Chen TC, Holick MF, Barger-Lux MJ.

Human serum 25-hydroxycholecalciferol responses to extended

oral dosing with cholecalciferol. Am J Clin Nutr 2003;77:204-10

PMID: 12499343

It can be downloaded free of charge.

I could be too brainfogged to be reading this paper correctly, but I

can't see where they measured 1,25-D, so I don't know how this

citation supports the statement in question.
