Rules:
-- PLEASE KEEP POST TITLES INFORMATIVE --
-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --
-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --
-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today/ . Twitter screenshots still need to be sourced or they will be removed --

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--
-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --
-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Hmmm. I'm less convinced of this being a fact.
There have been at least a couple of studies done on surfers in Hawaii who are semi-professional or who report getting at least 15 hours of sun exposure per week (and we're talking a lot of time spent with their entire backs to the Hawaiian sun here too) and these studies have shown a surprising amount of vitamin D deficiency in the subjects.
Most people aren't getting anywhere near that amount of sun exposure and I'd hazard a guess that most people aren't consuming much liver in their diet.
Vitamin D synthesis with sun on skin doesn't just convert all sunlight into vitamin D. Your body will stop synthesizing it at a certain point. It's not possible to overdose from sunlight.
I'm not saying that it's possible to overdose on vitamin D synthesised by exposure to sunlight, I'm just saying that I'm unconvinced that exposure to sunlight is in itself sufficient to meet vitamin D needs without dietary intake (especially for people who live a modern lifestyle where they don't necessarily get a lot of sun exposure).
I was told by my doctor that Iron plays a part in Vitamin D absorption, so these surfers could've been deficient in that or something else that interfered with their ability to metabolise Vitamin D
