[edit] B7
What is the asterisk on Vitamin B-7 about? (Someone should search the history & note any hints or lack thereof here, if no one has a quick answer.) --Jerzy·t 2005 July 5 18:00 (UTC)
[edit] Vitamin I
I doubt the hikers' standing-joke slang term "Vitamin I" for Ibuprofen needs any mention in the article, tho i am turning that redir into a Dab. --Jerzy·t 2005 July 5 18:00 (UTC)
- Actually, I'll take care of Vitamin I in Vitamin.

[edit] Microwaves
I was discussing vitamins with my roomie, who said that their chiropractor/physician had information saying that b-vitamins were eliminated when you microwave food. If true, that should go in this article. I'm not sure where I'd look that up, however.

[edit] A few things
1.Pangamic acid is better known as dimethylglycine: http://www.pdrhealth.com/drug_info/nmdrugprofiles/nutsupdrugs/dim_0097.shtml
2.Also,what is the reference for B-10 being Pteroylmonoglutamic acid and "other vitamins"? Pteroylmonoglutamic acid is synonymous with Pteroylmonoglutamate and Folic Acid ( http://www.google.com/search?q=cache:ymlKMg7d2wwJ:www.nap.edu/nap-cgi/morehits.cgi%3Fdisplay%3Dtext%26isbn%3D0309069890%26term%3Dfolic%2Bacid%26file%3D113-149.htm+pteroylmonoglutamate&hl=en&gl=us&ct=clnk&cd=11)so I made the Pteroylmonoglutamic acid page redirect to the folic acid page but maybe they should just change the name to folic acid.
3.One reference(though not a good one) says b-10 is PABA: http://www.althealth.co.uk/services/info/supplements/vitamin_b10_1.php So does the Vitamin wikipedia page: http://en.wikipedia.org/wiki/Vitamin another is http://newstaff.com/nutrientscatalog/designations.html but again there are no references!
4. Vitamin H is listed as inositol but most searches list both vitamin H and B-7 as synonyms for biotin: http://www.vitamins-supplements.org/biotin.php
^.Briggs who anounced B10(chick feathering) & B11(chick Growth) in 1943 belived them to be forms of Folic acid but not Pteryl-mono-glutamic acid as thay had a different line on chromotography than Pteryl-mono-glutamic acid or B12, also Pteryl-mono-glutamic acid dose not pass his isolation process or solubilities for B10 & B11 (PABA & 'Pteryl-hepta-glutamic acid' do). I have seen over 20 rerfrences of diffrent authors in Europe (French, Spanish & Italian; mostly french including Medical Dictionaries; non French ones refer to French Merk Index for B10 as PABA) claiming B10 is PABA. Very few in English. The refrence that says B11 is 'Pteryl-hepta-glutamic acid' is "Groot Woorden Boek der Geneeskunde(Encyclopedia Medica)" by H. De Haan & W. Dekker 1957 Bertei
Someone may also want to add some info about the relationship between PABA and folic acid ( http://www.drlera.com/vitamins/vitamin_bx.htm).
Although this has been suspected in the past, Vitamin B10 and B11 can not posibly be Vitamin R and Vitamin S. B10 and B11 are soluble in ethanol. vitamin R and Vitamin S are NOT soluble in ethanol. (some folates are not soluble in alcohol like folinic acid and PGA; some folates are soluble in alcohol like PHGA)Bertei
This page is a mess! --Renwick
[edit] Vitamin B8?
Here's the entire entry for vitamin B8:
Ergadenylic acid, or Vitamin B8, is a vitamin essential to humans consisting of the nucleic acid adenylic acid. Its deficiency decreases RNA synthesis, as well as ADP and ATP synthesis. A deficiency will inhibit the breakdown of food into energy and deteriorate hormone functions. This substance was not widely recognized as a required vitamin until recently, and, for this reason, the term "Vitamin B8" was also used by some researchers to denote inositol as a chich growth factor. Adalt defficiency is exreamly rare. ADP and other derivatives of Adenylic acid have also been called "Vitamin B8"
[edit] Contradiction
- The article ergadenylic acid presents vitamin B8 as a true vitamin, which contradicts the "B vitamins" article. Which article is correct?!!!!! --Transhumanist 07:54, 16 June 2006 (UTC)
There's no contradiction there. B8 is a specific molecule, "vitamin B" isn't. KonradG 14:10, 6 September 2006 (UTC)
[edit] Vitamin H and/or I
The sentence "Vitamin B7 (Vitamin I) – more commonly called alcohol soluble Rice bran anti digestive disterbance factor in Pigions; Inositol, Nicotinic acid, & Biotin are possibles" needs cleaning up. (I would do it if I knew what the author had in mind; "pigion"? a "possible"?) One site I have seen on the subject seems to say Vitamin I was an alternate name for Vitamin B7/biotin, which isn't so helpful since it doesn't say whether that makes Vitamin H = Vitamin I. I'm also intrigued by "Vitamin Bw – a type of Biotin but not d-Biotin". Boris B 00:22, 26 July 2006 (UTC)
This page has obviously been vandalized. There is no such thing as Vitamin I, though there is a sports team in Ithaca that uses that name. I wish I knew more about the subject to fix it, but I don't. The completely absurd entry for B-7 (Biotin) has survived numerous revisions.
I don't know enough about the subject either. I restored the B7 entry to what seemed to me what the second-last revision was trying to say. It looks to me that likely that paragraph is out-of-date; likely in the past they didn't know which substance was vitamin B7 and later they found out it was biotin, but I don't actually know that, I'm just guessing based on the information that's in the article. --Coppertwig 13:53, 3 December 2006 (UTC)
[edit] Poisoning
What about something on B-vitamin overdosing/poisoning? Anyone know anything about it? The Jade Knight 04:13, 28 October 2006 (UTC)
you may better refer to separate vitamins for details, since vitamin B is a collective terms for many kind of vitamins, and they have very different symptoms in either undernorishment or overdosing. Meaningless 03:47, 31 October 2006 (UTC)
B vitamins are water soluble, any excess is eliminated by the kidneys.... so no toxicity issues Jan 05/07 (KBS)
[edit] B7 and B9
I can't find any reference to Biotin being called B-7 or Folate being called B-9 in my Nutritional Biochemistry book, so I assume these are either very obscure names, or just incorrect. Does anyone have a citation for this? --Slashme 07:05, 1 February 2007 (UTC)
