Ivor Cummins presents a comprehensive look at the benefits of vitamin D and sun exposure, arguing that standard recommended levels are too low.

It's benefits are difficult to disentangle from those of healthy Sun Exposure though - the beneficial effects of D status may be hugely due to the sun exposure that got your D up! I use sun and UV sources to achieve my D levels as a result, not supplementation. Other key elements like K2, A, Mg, Ca etc are inextricably linked also, but here we focus mainly on D. Reverse Causality applies also - people who have inflammatory issues and are obese may drive down their D status, but data on this is sparse - but keep it in mind. Also important is that DAILY supplementation rather than big bolus dosing is used - the half-life of D3 is only a couple of days. This Seminar is of interest to Mothers & their Children particularly (e.g. see to segment), to avoid probability of serious chronic diseases, in childhood and beyond. The main message is that blood levels of D should be targeted towards healthy evolutionary levels, ideally through access to UVB / healthy sun exposure (NO burning). So to stress again: there is a lot of associational "correlation but possibly not causation" data in this, and there is every possibility that Sun exposure delivers more benefits than D3 supplements (by the production of many other photoproducts in the skin), and also the modern carb-inflamed/diseased population may be causal in driving down 25(OH)D status (e.g. the obese people with low D - is it their fat sequestering away the D, or is their inflammation driving down their status?)

On “High doses of vitamin D rapidly reduce arterial stiffness”
…curences 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: link to this 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…

On “Vitamin D deficiency and Covid-19 mortality [pdf]”
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: link to this video

On “Vitamin D, part 2: Shannon's story”
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.

On “Is vitamin D really a cure-all, and how should we get our fix?”
According to the study in the other HN link here, they made an error in calculating how much Vitamin D you need. The medical community also seems to think that 20 ng/ml is when the deficiency starts, when in reality it's more like 40. Some studies have shown that you can see benefits upwards of 60 ng/ml. Other research has shown that Vitamin D helps with sleep in the 60-80 ng/ml range. I've seen many people on Reddit say that their blood tests level came out at 5-10. That's crazy. Get your 25(OH)D level checked. Some of the studies that have shown "no improvement" from Vitamin D saw that result mainly because they were still prescribing far too little Vitamin D (yet still higher than the RDA…
