Elmer McCollum and Marguerite Davis identified Vitamin A in 1913. See Wikipedia article on Elmer McCollum for details. 216.222.180.142 (talk) 20:12, 11 July 2024 (UTC)

Should this phrase be changed to "essential to an animal"? Are vitamins relevant to non-animal organisms (other than e.g. plants being a source of vitamins for animals)? There is no mention of any non-animal organisms in the article. Averixus (talk) 08:08, 4 February 2025 (UTC)

Vitamin J redirected to Choline until I just now changed it to redirect to the obsolete name chart at Vitamin#Naming. That chart lists Catechol and Flavin for Vitamin J, but not choline. Should choline be added, or was that simply a long-standing error? I'm having trouble separating reliable web sources from AI slop. One reliable source I could find was [1]. It just says "Finally, vitamin J: Beneficial to guinea pigs but unneeded by people, it didn’t make the cut." and does say which compound that refers to. I couldn't find anything about guinea pigs on the three compound articles. -- Beland (talk) 20:49, 25 September 2025 (UTC)

The article refers to "Title 21, part III" when it intends to refer to part "111" - the section of the Code of Federal Regulations relating to current Good Manufacturing Practice for dietary supplements.  — Preceding unsigned comment added by ~2025-34015-53 (talk) 17:04, 17 November 2025 (UTC)
