this doesnt pass the correlation vs causation smell test for me. i suspect VID correlates well with COVID comorbidities, like a sedentary lifestyle, hypertension, and weight problems. the opposite is also probably true, that people with good vit D levels correlate with healthier lifestyles and fewer comorbidities.

It's not even correlational. They didn't even have a group of non-COVID patients to compare to, which would have been really easy. They could have looked at non-COVID ICU patients as well and did not. That would have at least been correlational.

Interesting thing... Vitamin D is one of those things that, when vitamins come up on HN, you will often hear the refrain that "it's the one vitamin that large numbers of people are actually deficient in and ought to supplement." I've heard that many times over the years and I have taken a Vitamin D supplement on and off (more off than on) over the years. When this COVID-19 thing first hit, I had a physical scheduled…

Totally not a placebo. Vitamin-D fortified milk was a necessity (for me) in Portland to avoid depression.

Well yes, Vitamin D is pretty hard to come around in the northern hemisphere so no surprise there. Mind you, it's far not the only thing - magnesium, zinc, selenium are just a few which most people are missing. I mean unless your diet consists entirely of tuna and salmon probably. Over the last few years, I've stressed significantly on my physical health(after being very overweight for the most of my adult life and n…

> People with indoor jobs and hobbies are probably not getting enough. I argue that if you go outside and wear the appropriate sun protection—long pants,long sleeves, neck covered, broad rim hat, and wear sunscreen on the exposed parts—you can't get enough sun exposure to produce enough Vitamin D.

If you do get enough sun exposure without the protective clothing you'll probably damage the shit out of your skin.

I live in south Louisiana and I am often outside without a shirt or sunscreen on, my skin is not damaged.

> if you are in a office job you are def. not getting enough vitamin D. I think this really depends on location and lifestyle. Anyone in a Mediterranean or sunnier climate that spends more than 30mn a day outside will be fine

I spend lots of time outside and I live in California. I still had life-long vit D deficiency, probably since birth. No idea why, might be something genetic. The only way I could figure it out was via blood tests, spaced a few years apart. First time the doctor said "hm, you're pretty low on vit D, you should supplement it". Second time, it was more like "you're really low and you should take XXX amount each day, NOW…

Vitamin D is not absorbed instantly when exposed to the sun. Soap and hot showers removes what is left so levels are also affected by personal hygiene habits.

You’ve got the causality the wrong way round

Yeah, and Italy, Spain, and France are some of the sunnier countries in Europe (compared to Germany, UK, Belgium, Scandinavia, etc). If anything I would expect vitamin D deficiency to be less common there.

I don't know about Spain, but in both Italy and France the regions most affected are the northern overcast places. The impact around the Med is much smaller, despite much much more retirees

Don't forget Ecuador which is literally on the equator and experiencing a major outbreak.

It's the wet season in Ecuador

Do you mind sharing which one it is?

Oh my. As per usual Gwern, an amazingly detailed and long post about magnesium. I skimmed it in about a minute and just got a sense that I would need an entire afternoon just to properly read it. I don't know how he does it, frankly. But I'm thankful.
