For people with sleep disorders.
The current recommendation is keeping serum levels at least above 30, and more like 40-60. Many many people aren’t in that range.
The key is to go outside, get some natural light and sun on your skin. Most of us reading this are vitamin D deficient year after year.
Covid has had an advantage on anyone lacking proper vitamin levels.
Earlier quoted context omitted.
Apparently D3 inhibits production of melatonin. Can't remember where I read this so not a hugely useful comment but I promise I didn't just make it up! Anecodtally, I've also experienced similar issues taking 1000 IU D3 before bed and having trouble sleeping. I moved the dose to the morning and Boom!, good sleep. Edit: Here is the study. https://pubmed.ncbi.nlm.nih.gov/23665342/ - only a single study but still intere…
I take 2,000 IU of Vitamin D3 nightly right before bed and have no trouble sleeping.
My vitamin D level is only optimal when taking an average of 11000 IU / day (D3 + K2). It hasn't improved my sleep quality. As an example, I woke up at 3:30 am this morning and feel like I haven't slept at all.
Wake up at sunrise, go to bed at sunset. Anything else is going to cause problems.. or you are simply a night owl, which is ok. The key is to go outside, get some natural light and sun on your skin.

That's at least 10 hours of sleep per day, for a large part of the year.
It's also no sleep at all, in some parts of the year, for some countries.

Try doing the same in New York, to say nothing of places like Stockholm.
Getting outside a bit is a great advice most everywhere, though. It's not always going to produce a lot of vitamin D, when you wear clothes mostly covering your skin, but it has other advantages.

50,000 IUs every 15 days for 8 weeks. I wonder if it would have better effects if they were given 3-4k IUs every day
Megadosing D3 on the rare occasion is similar to gradually taking normal amounts as far as serum levels go. It's common to see in studies. You wanna be careful doing it without supervision obviously but I don't see why there would be a difference in a study if the hypothesis is that deficiency is causing the sleep problems. As far as the study goes, it was significant at a p 0.05 level so will wait for replication.
