Proper supplementation (read: not what is currently recommended) of Vitamin D was found to reduce all-mortality causes (including cancer, diabetes, heart attacks, etc) by as much as 50%-70%. To get to that level of 40-50 ng/ml 25(OH)D, you need around 8,000-12,000 IU per day (depending on body mass). It was also found to reduce flu occurences by as much as 70%. This is starting to look like a super important vitamin, even for "healthy individuals that work outside" - let alone everyone else that stays all-day indoors. It also seems to have a huge effect on sleeping well, as it's apparently what the body needs to repair itself properly at night. I highly recommend these videos: [VIDEO] [LINK] Also, you should combine it with Vitamin K2, another hugely important vitamin most of us are likely lacking, that works in conjunction with D: [LINK] [LINK] [LINK]

More studies referenced here, also showing ~55 ng/ml being optimum for maximum health benefits. The current recommendations are way below that. Well worth to watch the whole video: [VIDEO]

Few months ago I head how vitamin D is associated with COVID-19 outcomes and went into a rabbit hole to find more information about wtf is Vitamin D, and how our bodies use it/need it. There are two videos I found particularly informative. 1. [LINK] Cost/Benefit of Optimal Health with Sunshine Vitamin D William B. Grant, PhD 2015 2.
