Milk

Milk is listed as a source in both the Vitamin D and Forms sections, but not in the sources section. Is this a deliberate omission (and if so why?) or an oversight? AFAIK milk provides around 400IU/litre, but I have no reliable source. Can someone help me out here? 87.115.6.214 (talk) 14:45, 12 November 2012 (UTC)[reply]

Milk has amounts of D that are extremely variable unless radiated with UV or fortified with D3 to some uniform number. It depends on what the cows ate, how much UV they got, and so on. That's why neat little figures can't be given. S B H arris 04:06, 12 February 2013 (UTC)[reply]

Second heading paragraph - original content??

There is only one citation in the second paragraph, and I just finished reading the entire paper by George Wolf. The majority of the second paragraph is content that is not found in this paper. 64.207.224.18 (talk) 16:37, 15 March 2013 (UTC)[reply]

I think you mean the second paragraph of the lead (the text at the top of the article). If so, please remember that the lead is just an intro that summarizes what is in the body of the article. You should find everything sourced in the body of the article. (sometimes we do ask that statements in the lead be sourced, if they are controversial or are summaries that amount to "original research" and cannot stand without sourcing. If you don't find sources in the body, then it is reasonable to complain, or better, put a "citation needed" tag in the body of the article, or even better, see if you can find sources and add them...

Sorry about that, yes, the lead. Got it. Thanks! 64.207.224.18 (talk) 19:34, 15 March 2013 (UTC)[reply]

Subscript?

In this article the various forms of vitamin D are sometimes written subscript (D₂, D₃) and sometimes not (D2, D3). I can't help but wonder: does this donote different compounds or is it just a typo? Project Osprey (talk) 11:22, 25 April 2013 (UTC)[reply]

Resources

I feel that this article needs incorportation of the information on oral and intravenous Vitamin D supplementation during its deficiency. The role of a single dose of Vitamin D intramuscular depot preparation needs to be included. The following reference would prove useful in this regard.

Einarsdóttir K, Preen DB, Clay TD, Kiely L, Holman CD, Cohen LD. "Effect of a single 'megadose' intramuscular vitamin D (600,000 IU) injection on vitamin D concentrations and bone mineral density following biliopancreatic diversion surgery". doi:10.1007/s11695-009-0024-3.

That source is subpar under MEDRS - you should find a review in the medical literature that discusses this. If you do use it (and you should not), whatever content you add to the article must be strictly limited to what the article says, and go no further. Jytdog (talk) 17:59, 29 June 2013 (UTC)[reply]

Vitamin D Not At All A Vitamin But A Hormone

So I was listening to a lecture on the history and function of Vitamin D on youtube and the lecturer said that Vitamin D is not a vitamin but it was thought that it was because mushroom sourced D2 cured rickets. However, Vitamin D has no nutritional value and function as a hormone. Nowhere in the article it is specifically mentioned. Its kind of "eaten around the bush". Would anyone have any objections to changing the article to reflect that Vit D is not a vitamin but a hormone?173.180.7.3 (talk) 12:53, 25 July 2013 (UTC)BeeCier[reply]
