However, taking 3 vitamins is almost entirely harmless.
Vitamin overdoses can be serious in the worst cases. https://en.wikipedia.org/wiki/Hypervitaminosis_A https://en.wikipedia.org/wiki/Hypervitaminosis_D

> Since taking a basic multi-vitamin is good anyway.... Could you elaborate on that? I thought that taking vitamin supplements without a recommendation from a doctor is just a way to have very expensive piss. Most of the things that get in, are removed from the body without being absorbed.
Americans have the most expensive piss in the world. Yes, unless you have good reason to think you have a deficiency, supplements are a waste of time and money. And even if you do have reason to think you might have a deficiency there are often better (usually dietary) ways to address it.
Was this known early on about COVID? Early on in the lockdown I noticed that these vitamins were among the kind of weird items completely cleared out of stores. People were very selective... initially all FHD laptops and Chromebooks were gone, along with power strips, ibuprofen, hair clippers, etc.
Powerstrips are necessary for makeshift home offices which are now everywhere. Hairclippers are important for people who regularly like haircuts. I usually go months, but know plenty of people who go weekly or bi-monthly.
Even without research saying vitamins have an impact on this disease, I think people would be grabbing anything with the potential to help (vitamins and certain medicines).

Perhaps Vitamin D status is just an indicator of adequate sunshine on the skin. This would explain why people with low vitamin D are more susceptible, yet supplementation with Vitamin D is ineffective.
I've seen two theories floated: 1. Vitamin D as a side effect of sun exposure is not itself the important indicator. Instead, some other biological response increases immune response simultaneously. Hence, D supplementation is itself copying the wrong response. 2. Vitamin D deficiency is caused by illness, hence it actually doesn't affect mortality and the relationship is not casual.

Presumably it's relatively easy for a lab to run a panel of tests on me and say "you're deficient in X, Y, Z; try eating more A B C; spend 30mins extra a week outside; drink less alcohol". How easy is it too get such tests (in UK), I'm surprised we don't seem to have anything like this as part of our health system. I've had blood pressure and height/weight taken a couple of times (I'm middle aged). But that's about a…
Just measuring those 4 costs 83€ in a laboratory in Vienna. And there are more measurements one should probably take! And you need to test them more than once to see if supplementation works and you are not getting too much. That's not cheap...

Vitamin D deficiency is very common especially in people who spend their daytime hours inside and also in dark skinned people living in northern latitudes. In the UK doctors recommend everyone takes a vitamin D supplement in the winter.
I've never heard this, where is it recommended?
N=43 (17 given vitamins vs 26 not) Highlights: "Significantly fewer DMB patients than controls required initiation of oxygen therapy subsequently throughout their hospitalization (17.6% vs 61.5%, P=0.006)." "DMB combination in older COVID-19 patients was associated with a significant reduction in proportion of patients with clinical deterioration requiring oxygen support and/or intensive care support. This study supp…
> Since taking a basic multi-vitamin is good anyway, it seems wise to do that. There is no evidence that taking a basic mulit-vitamin has any benefit for average people. Depending on the composition of vitamins it can be harmful [1]. [1] https://www.cochrane.org/CD007176/LIVER_antioxidant-suppleme...

Many things are almost entirely harmless, but before recommending you do them anyway, you probably want to look at whether there's any point. Turning round in a circle three times before you leave the house is almost entirely harmless, and there's no evidence that doesn't stop you getting coronavirus...
Turning round in a circle three times also doesn't improve your health in general. Getting the right vitamins does improve your health.

Many are toxic (vitamin D included) in unsuitable amounts, that’s probably too strong of a statement.
The study mentions 1,000 IU D3 dosage. A quick google turns up a rough figure of 60,000 IU "daily for multiple months" can become toxic. You're probably right, most things taken at 100x the normal dose for long period of time are toxic. (Water included)
While possible, it does seem unlikely.
