Vitamin D improves survival in Covid-19 elderly patients

Friendly reminder: vitamin D3 can affect sleep if taken later in a day. I tend to skip if I forget to take it before noon. Also, D3 without additional K2 may lead to calcium excess.

From what I googled I couldn't find evidence for Vit D causing sleep issues taken at night - I did find articles suggesting that taking with a meal helps absorbsion - https://www.healthline.com/nutrition/best-time-to-take-vitam...

While there are studies on 25-OH-D metabolism impacting melatonin production, I can only find studies done with Multiple Sclerosis patients [1]. There are also studies showing that LOW levels of 25-OH-D may have negative impact on sleep [2][3][4]. While I am unable to present scentific evidence, I would like to state that for me - personally - taking vitamin D3 in the afternoon has similar effects to ingesting caffeine. I have no reason to believe that I might be suffering from Multiple Sclerosis. Without evidence you are free to ignore it as a placebo/nocebo effect. YMMV based on age, ethnicity, sunlight etc.

The "take with meal" instruction is common with substances requiring fat for absorption/bioavailability. Dietary fat increases vitamin D3 absorption [5].

One more friendly reminder: If Vitamin D dosage is above 4000IU, same amount of Vitamin A should also be supplemented to avoid Vitamin A deficiency (e.g. eat liver). It's also antiviral, so it sounds like a good idea anyway.

Doctors of "holistic" medicine. One of the people in that video is also a staunch anti-vaxxer.

So, broken clocks, and all that.
