If you have been under the assumption that raising Vit D levels by supplementing will help with covid outcomes, you should watch this. TLDW it seems it has nothing to do with vit D levels , but everything to do with another spectrum of sunlight (near-infrared). *promote

So if you synthesize your own through exposure to sunlight, you’re good? Or at least better off?
Is it possible that it’s not the delivery method, but the systems that use vitamin D being healthy beforehand vs being supplemented after the fact? Maybe it takes a while to get those systems healthy, and supplements don’t help with that.

Edit: Maybe, since the same receptors are used to metabolize vitamin D as to infect a cell with covid, those receptors being “full” might be what’s stopping infections, and dosing with vitamin D after infection doesn’t magically replace the Covid with vitamin D? Not really about vitamin D or why you need it, just about the mechanism the body uses to use the vitamin D? Biology is intricate, and why things work and how is not always clean and simple.

Melatonin? Then why aren’t people with more melatonin, people of color, nearly immune? Why are island nations like the Virgin Islands still having outbreaks today? Why were Southern states hit just as hard or harder than northern states? Many questions here.

His explanation seems to confirm this. If your cells produce vitamin D efficiently, they are less prone to infections, if you artificially add artificial vitamin D, it helps with the cellular functions, but the processes that should be producing it are still suppressed, possibly more because your body isn’t triggering them due to low vitamin D levels. It’s less about overall vitamin D levels than about having healthy systems that properly produce and utilize it….at least that’s my takeaway.

It’s not just about sunlight..it’s about diet, overall health, sleep, etc. biology is complex, and we always want a simple solution. There isn’t one most of the time, and our attempts to simplify only make things worse. Eat well, sleep well, get some sun, get some exercise, and you’ll be as safe as you can be naturally….then try supplements in addition, not instead.

I get plenty of sun, and my windows are from the 50’s. It definitely makes me feel better to get sun, but there’s a limit. Don’t just go sunbathe in Arizona, use your brain.

I knew I should have stayed in Florida.

What I don't understand is how this controls for other factors? People who have a high Vitamin-D tend to be healthier in general. If you give unhealthy people Vitamin-D supplements -- that won't help their outcomes.
