Interesting. Vitamin D is indeed a hormone, but I disagree that supplemental vitamin D has no effect. I actually had to lower my Vitamin D intake, my Vitamin D-25 hydroxy panel came back elevated. 
On the other hand, my wife has several.health conditions...lupus, hypothyroidism, and RA...and has to take the 50k iu caplet once as week. It's the generic, I think the brand name is Drisdol? Anyway they had to halv her dosage, so the pharmaceutical version does something. 
Always good to see studies from both perspectives though!! 
Edit: We do live in the sunny South?
