Where does Biotin occur naturally, if anywhere? The article doesn't make it clear Coyote-37 14:23, 5 October 2005 (UTC)

I agree, and furthermore I think this article as a whole is too technical. Joe average seeking information on Biotin will be befuddled.
The Italian article mentions milk (human and bovine), egg yolk and seafood, and says that in vegetables the bioavailability is low. I don't agree that the article is too technical. Icek 16:23, 30 April 2007 (UTC)


Note to the moderators: This last paragraph required editing. It was written in ignorance and was offensive to those of us who not only use alternative therapies and its components, such as apricot kernels, but also deal with a great many people who have indeed cured themselves of cancer and various other diseases as a result of their use. It would seem the writer of this overview chooses not to thoroughly research the subjects of his drivel before imposing them upon unsuspecting knowledge seekers. Highly irresponsible. This person should have his privileges revoked and all writings should be thoroughly reviewed for similar content. Please remove this message once read. Many thanks.

This is good!!

[edit] Copyright violation?

Some of this article seems to have been "adopted" from http://www.pdrhealth.com/drug_info/nmdrugprofiles/nutsupdrugs/bio_0035.shtml and I don't have the time to find the copyright template. MeekMark 02:32, 1 August 2006 (UTC)

It seems it has been removed/rewritten in the meantime, so there should be no copyright problem now. Icek 11:23, 4 August 2007 (UTC)

[edit] Poor Wording

"Biotin deficiency is a rare nutritional disorder caused by a deficiency of biotin" What is this sentence trying to say? Maybe this can be rewritten if the author's original meaning is known. nChanq 21:52, 22 August 2006 (UTC)

"Vitamin H may also refer to haloperidol"- this is confusing, inaccurate and may be removed. If needed, origin of "H" in vitamin H may please be mentioned. We need more modern information and state clearly that it is an enzyme cofactor.Ck.mitra 07:39, 30 August 2007 (UTC)

[edit] What is biotin supplement made of?

I have been unable to find info on the manufacture of biotin for human supplementation. In lay terms, how is biotin produced, from what materials? Thanks. 74.38.116.21 19:28, 12 November 2006 (UTC)V.B.

I have the same question as the guy above, and also, can biotin be synthetically manufactured for use in vitamins, supplements, etc.? I also agree with nChang, that sentence makes no sense. 141.156.142.13 22:11, 26 November 2006 (UTC) AnimeKing99

While I don't know how it is manufactured commercially, it certainly can be manufactured. One path starts with cysteine, which is also used by organisms as a building block for biotin. See here for (unfortuately only the first page of) an article about that synthesis. And you could try searching for biotin "total synthesis" in Google Scholar (which returns only scholarly articles, but often without free fulltext access) or in a normal search engine.

[edit] Links for Biotin Info

Here's two great websites that have lots of info on biotin that may not be mentioned here: [1] and [2], the first link is for really smart people, it's really complicated, but the second link is a lot easier to understand, and lists a lot of the places where biotin occurs naturally. Hope that helps!! ;) 141.156.142.13 22:24, 26 November 2006 (UTC) AnimeKing99

(PS: If you have any burning questions that you can't find the answer to about biotin, ask me! I know a lot of stuff about it!!)  :)


[edit] Excessive consumption of raw egg-whites

deficiency can be caused by excessive consumption of raw egg-whites over a long period (months to years)

What constitutes "excessive consumption"? 2 eggs per day? 5? Icek 17:04, 5 April 2007 (UTC)

I believe that two raw egg whites per day can, in fact, be considered excessive consumption for many people. In general, the more raw egg whites you eat, the faster the symptoms appear. A dozen raw egg whites (which provides about 200 Calories or 50 g protein) each day might produce symptoms in as little as two weeks. Most docs prefer that their patients avoid eating raw egg whites entirely. WhatamIdoing (talk) 00:00, 17 December 2007 (UTC)
Hmm... to bind 0.3 mg biotin you should need the avidin from 11 eggs (see my comment at Talk:Avidin#Digestability). 2 egg whites should bind about 0.05 to 0.06 mg - is this already harmful? Most docs probably prefer a wide safety margin. Icek (talk) 17:22, 29 December 2007 (UTC)

[edit] Excess symptoms

The symptoms described for excess of biotin are not documented anywhere. Alopecia is a sign of biotin deficiency, not excess. At least google it.

[edit] RDA

RDA, ADI or the like. Since it is produced by intestinal bacteria surely those on antibiotics may require supplementation? --41.241.192.53 (talk) 10:31, 20 November 2007 (UTC)
