Can anyone here help demystify how "oral calcifediol (0.532 mg)" maps to an equivalent amount of Vitamin D in the form you can buy in a drugstore?

I don't know, but I take 5000 ius a day and because of my gastric sleeve I'm still somehow deficient. So upped it to 7500 ius by adding a multivitamin. I'm also O positive (which means I won the damn blood lottery for covid hehe), but overweight, so gotta hedge my bets as best as I can. I also take zinc.

Seems like a ridiculous claim when I'm sure almost absolutely everyone would like to get out of this mess.

It shouldn't be hard to sit for a moment and think of some people who would certainly like for there not to be a treatment consisting of ~$3-5 worth of off-the-shelf, completely unpatentable medicines and vitamins. There are absolutely some powerful vested interests in not seeing an easy treatment for this disease, or, by the same logic, pretty much any other disease either since there's nothing special about this on…

The original claim said "invested in the belief that there is no treatment for it", not "no inexpensive treatments".

What you are rebutting is not against what OP is claiming.

> My understanding is that it hasn’t been shown for elevators. I think ... Where are you getting this understanding? You are asking for evidence while providing none yourself...

Well the absence of anything is the default, so the burden of proof is on the person making the claim. I had read that somewhere in studying transmissions in NYC where elevators are common. I don’t remember where, it was a while ago.

There is a lot of evidence that close quarters, inside contact is very risky for transmission; every country in the world is operating under that assumption, indeed most are passing laws based on this. There is zero reason to believe that elevators ... both close quarters and inside would some how be an exception.

You've claimed that elevators are an exception to the established guidelines without evidence and are now claiming that that other, well evidenced, claim some how needs additional support to be applied to elevators.

Non-white skinned people: sunlight may not be enough to increase your vitamin D. https://www.google.com/search?q=dark+skin+vitamin+d+minutes

Is there a scientific classification system for evaluating how light vs. dark a person's skin is? I'd like to know how much my relatively darker skin is preventing vit D uptake / creation in the body

I don't think skin color is very relevant if you live a modern sedentary life that implies most of your time is spent inside: you're probably deficient whatever your skin color is.

IMHO it would be best to test your vitamin D level anyway and act accordingly.

Hydroxychloroquine is a zinc ionophore which helps zinc get into the cells in your lungs and slows the viral replication. It was not designed to be used this way, it just happens to work. This is mostly useful before your viral load is high. Same goes for Quercetin, also a zinc ionophore. They are good proactive measures to slow down the viral transcription before you reach a critical stage. It won't help everyone, e…

Wiki says that "Hydroxychloroquine is being studied to prevent and treat coronavirus disease 2019 (COVID‑19), but all clinical trials conducted during 2020 found it is ineffective and may cause dangerous side effects." https://en.wikipedia.org/wiki/Hydroxychloroquine

In the interest of free speech, here's a PDF with all the positive trials for HCQ:

My understanding is that it hasn’t been shown for elevators. I think this is because of the required time to breathe in a minimal viral load. Do you have evidence otherwise?

Yes I heard planes as well surprisingly safe relative to choir practice. Environments where lots of droplets are created are less safe...

planes have two things going for them: good air circulation with filtration, and mask-wearing is well enforced.

Greater than 70% of African Americans are suspected to be Vit D deficient. Definitely worth getting tested if you can [1] especially if you live in the more northern latitudes. Doubly so during winter. [1] with the note that generally insurance is a real PITA with vitamin D testing. The trick usually is to list as a diagnosis code a previous history of low vitamin D. Yes it’s like a catch 22. You need prior testing s…

>generally insurance is a real PITA with vitamin D testing

FWIW, vitamin D has been among the things tested when I have my blood work for an annual physical and never had any insurance issue about it. And I do take supplements because it was low.

Surly now it's time to just start giving everyone some free vitamin D. Best case scenario: Less dead people. Worst case scenario: We all have healthier bones.

The worst case scenario isn't 'healthier bones'.

It's kidney failure - https://www.cmaj.ca/content/191/14/E390

Or fatal hypercalcemia - https://link.springer.com/article/10.1007/s12098-016-2109-z

And so on.

I frankly think its irresponsible and facile for anyone to suggest there are no downsides to high doses of Vitamin D. This stuff is available OTC and a lot of folks are just gonna dose themselves ad libitum here.

I know people subscribing to the Vitamin D religion don't like to hear this, but this is one of those claims about Vitamin D that has been tested - and actually isn't true. https://www.medpagetoday.com/endocrinology/osteoporosis/8183...

Previously on HN, a physician shared some thoughts on treating Vitamin D as a medication and not as a dietary supplement:

Part 1: https://news.ycombinator.com/item?id=24138590

Part 2: https://news.ycombinator.com/item?id=24261948

To summarize - popping in large doses of Vitamin D is not exactly safe.
