Page moved to Talk:Vitamin B12. But there may be some cyanocobalamin-specific related issues still to treat here, so I've left it as a TALK page, not a simple redirect.

[edit] B12 the band

I have no objection to it being a dab/direct in B12 pages, but putting it in here in cyanocobalamin, is just too much. I'm taking it out. SBHarris 04:06, 4 December 2007 (UTC)

There's actually a template that is normally used for this purpose. The reason is that B12 redirects here, and it might not be what people expected (for example, when someone links to the redirect thinking about the band, or someone just types B12 in the "Go" box). The template is {{redirect}}, and results in

"B12" redirects here. For the electronic music duo, see B12 (band).

I think the template should be added. --Itub (talk) 08:26, 9 December 2007 (UTC)

I've changed B12 into a redirect to vitamin B12, which seems to solve the issue. --Itub (talk) 10:16, 9 December 2007 (UTC)

[edit] Cyanocobalamin Toxic

I've moved this section here until it can be verified and referenced:

It has been found to produce cyanide in your system in the formation of it into methylcobalamin, which is used by the body. This cyanide can react with potassium to form potassium cyanide (KCN) which is highly toxic. So one should use good forms of Vitamin like methylcobalamin, which is found naturally in nature, and can be readily used by your body. :) _{This was written by a college student very much into food, and in no way can back up these claims. But, scientists have written on the subject, and i hope someone can do some research and correct me if I am wrong in any way.}

In response to the original query, is it reasonable to expect potassium cyanide to remain undissociated in the body? Does the potassium make any difference at all? --Rifleman 82 (talk) 13:57, 7 January 2008 (UTC)

No, there will be no specific cation associated with cyanide in a biological environment, but the toxicity of cyanide is independent of the cation associated with it anyway. The important issue here is: Does cyanocobalamin generate any free cyanide under biological conditions; and if so, is the amount generated enough to have negative health consequences? Any statement we make is this article relative to this question needs to have a reliable source. -- Ed (Edgar181) 14:14, 7 January 2008 (UTC)

This article might shed some light. (I'll read it when I have more time): PMID 7090966. --Rifleman 82 (talk) 14:20, 7 January 2008 (UTC)
