Unreliable for Wikipedia's purpose, and quite probably a statistical freak in reality.[1] Bon courage (talk) 16:16, 29 December 2022 (UTC)Reply[reply]

A lot has been published on muscle strength and vitamin D with varying findings. See some meta-analyses PMID:31729817, PMID:34405916. Jrfw51 (talk) 11:36, 30 December 2022 (UTC)Reply[reply]

That talks about https://www.ncbi.nlm.nih.gov/pubmed/35082139?dopt=Abstract. Unrealted. 2A00:1370:8184:9B6:B686:A965:575D:B9E8 (talk) 17:24, 30 December 2022 (UTC)Reply[reply]

Again, not WP:MEDRS. Bon courage (talk) 17:31, 30 December 2022 (UTC)Reply[reply]

Again, not a review of WP:MEDRS sources is a separate requirement. 2A00:1370:8184:9B6:2E9A:E14E:374B:FF2B (talk) 10:09, 10 January 2023 (UTC)Reply[reply]

“Generally” Recognized… 4K IU is safe.[edit]

I removed “generally” from the following phrase: “…it is generally recognized that daily supplementation of 4,000IU is safe.”

@Shibbolethink reverted my edit, commenting: “generally regarded as safe is a technical term supported by the source.”

Yes GRAS is a technical term, but GRAS is not the phrase used in the preexisting text. Additionally, the preexisting cited sources do not specifically support the preexisting text or “GRAS” and one of the two (“Why the IOM recommendations for vitamin D are deficient”) instead support my edit:

“the panel raised the upper-level intake “TUIL” to 4000 IU/day. (The report acknowledges that intakes up to 10,000 IU/day are probably safe for everyone and applied an uncertainty factor10 to that 10,000-IU figure to generate the 4000-IU TUIL. It is important to stress that the TUIL is not a limit but instead constitutes an assurance of safety for such an intake.)”

I’ve reverted to my version. JustinReilly (talk) 01:13, 22 February 2023 (UTC)Reply[reply]

The sources were hopelessly old; have updated. Bon courage (talk) 06:41, 22 February 2023 (UTC)Reply[reply]

That is true. 4000 or 5000 IU per 24 hours are safe even if taken with magnesium glycinate and Omega or other fat. More should be taken with K2 only. Of course it doesn't apply to the tan salons where you can get even 50000 UI and it will be safe. Valery Zapolodov (talk) 16:11, 30 April 2023 (UTC)Reply[reply]

Starting preparation for submitting for Good Article[edit]

Starting some ref, copyediting and content checking before submitting this for Good Article. I will submit after I reactivate and complete my GA submission for Vitamin E. If successful, vitamin D will be the last vitamin article raised to GA. Going forward, all improvements to this article are welcome. David notMD (talk) 17:02, 19 March 2023 (UTC)Reply[reply]

Vit D levels[edit]

@Zefr Hey, levels of Vit D is defined differently by different organizations and if you don't understand importance of it, then just back off a bit and stop reverting the edits. Kolma8 (talk) 23:45, 25 August 2023 (UTC)Reply[reply]

The sentence was clear in the prior version. You are warring over sentence structure. You have been warned on your talk page for disruptive editing and violation of the 3-revert rule. Zefr (talk) 23:52, 25 August 2023 (UTC)Reply[reply]

Telling someone to back off a bit and stop reverting and continuing to edit war yourself is not gaining the required consensus in support of your edits. MrOllie (talk) 23:57, 25 August 2023 (UTC)Reply[reply]

D3 versus D subscript 3[edit]

In the article, why does it say "vitamin D3" and not "vitamin subscript 3" in, "The activity of calcifediol and calcitriol can be reduced by hydroxylation at position 24 by vitamin D3 24-hydroxylase, forming secalciferol and calcitetrol, respectively." ? It looks wrong to me, and yet there's a link supporting it. Polar Apposite (talk) 18:14, 26 September 2023 (UTC)Reply[reply]

Looks you cannot follow links. https://www.enzyme-database.org/query.php?ec=1.14.15.16 Valery Zapolodov (talk) 16:55, 5 November 2023 (UTC)Reply[reply]
