I could not readily find the study online in a brief look, but from what I did see in the NN article and elsewhere I cannot tell what form of Vitamin D the study used. Obviously D3 is the much preferred form. Then again, the very best thing to do is to get as much of your desired D in natural form from sunshine and when seasons or other reasons prevent that from happening supplement with D3.
I am a big, big fan of Vitamin D, but have to say that the more positive studies about supplemental Vitamin D I see coming from the folks who ifrst scared us out of the life-giving sun and had us slathering on carcinogenic sunscreens for decades, the more I wonder "what is the catch?"
Fortunately for me I live far enough south to be able to get plenty of direct and indirect sunshine most of the year - though often I don't look up from the dang computer until it's dark out. Gotta change that . . .
All the best,
Tony
