Damaging high doses can be as little as a few minutes in the Australian summer so I think it's fair to keep that in mind. On your evolution comment, most Australians don't have dark skin, but the ones who were here before Europeans do. I think that is a good indicator that the body is adjusting to something harmful. On the other hand, many dark skinned people in Britain aren't in a climate they evolved for either. We…

Adding some information for those interested in more precise numbers. This paper [1] has the recommended exposure time for a few cities in Australia. If you live in the same latitude, as long you live in the same latitude, this can be used as a guideline. https://staging.mja.com.au/system/files/issues/194_07_040411...

That's a really interesting link.

From the table there, for example, in Townsville in summer, with 11% of your body exposed, it takes just 6 minutes to synthesis 1000 IU of vitamin D.

A fair-skinned female friend who studied at James Cook University used to complain she got sunburnt walking between classes... So DWG, if you read this, apologies for telling you off for exaggerating!

A psychiatrist I saw multiple years ago told me to start taking Vitamin D. I went more or less blindly with 5,000 IU after reading some internet articles. I got my blood checked last year and decided I should probably actually know if I'm doing too much or too little. I was within 5% of the middle of the healthy range for vitamin D levels. For reference, 5,000 IU is >800% the FDA daily recommended value. People with…

Okay now I'm wondering if I should go get tested for vitamin d deficiency. I live in Colorado and therefore we have a lot of ultraviolet light and I do get outside as much as possible. However I'm wondering if that's still not enough. Seems reasonable that it's not based on your experience.

I live in Colorado, though I definitely don't try to get outside as much as possible. If you have symptoms of deficiency, nothing wrong with asking for testing vitamin d levels when you get a blood test. If you don't have symptoms, nothing to fix.

The next paragraph is even more interesting: > A colleague of mine and I have introduced vitamin D at doses that have achieved greater than 100 nmol/L in most of our patients for the past number of years, and we now see very few patients in our clinics with the flu or influenzalike illness. In those patients who do have influenza, we have treated them with the vitamin D hammer, as coined by my colleague. This is a 1-…

An interesting thought experiment is would a video showcasing this paper risk being be banned on YouTube? I'm not going to bother checking if the WHO has a Vitamin D recommendation; but recommending many multiples of the FDA dose probably counts as misinformation.

I think a more likely reason for a ban would simply be that the Vitamin D connection was being highlighted by lockdown skeptics for quite some time already, as part of investigating the Swedish outcomes. The problem is that to highly liberal Google employees it might look 'racist' because the Vit-D connection came out of trying to figure out why Swedish migrants were over-represented in ICU cases, also African-Americans.

For instance, in this comment from six days ago I write about a possible vitamin D connection:

Could this explain why the pandemic seems to be worse in NY compared to California and Florida?

I think that's about public transit vs automobile usage

SF public transit usage is high. Also, the burrow hit hardest in NY is Staten Island, which is very car heavy.

> For reference, 5,000 IU is >800% the FDA daily recommended value. Unfortunately the daily recommended value was established erroneously and should be much higher. Many research papers mention this. For example: > The Institute of Medicine recommendation for adults younger than 70 years of age is 600 IU of vitamin D daily. We are told that this would achieve a level of 50 nmol/L in greater than 97.5% of individuals.…

Unlike software developers, doctors, in my experience(friends and docs I have gone to), don't seem to have the same open mind about things in their field. At least the one's I know. It might seem foreign to us because a lot of our job is to keep an open mind and constantly question the status quo. Doctors tend to dismiss things immediately and unless you push you won't even get them try something that is harmless. I started going to a primary care physician a decade ago that actually listened, didn't rush me and kept an open mind. He was much younger though. Safe to say though I still go to him. Other doctors young and old that I've been to have not been the same.

That is interesting. As a generality I’ve found software developers to be some of the least open minded people. Perhaps a small bit amongst themselves (though the endless disagreements indicate it’s a very small bit), but when interacting with anyone outside the industry regarding some aspect of the industry, open mindedness is essentially non-existent. Perhaps it is the same for doctors interacting with patients.

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…

A lot of us actually know of the connection from previous experiences with the Flu. What it seems to really do is to clear out the cough that comes after the Flu when the cough/sorethroat tends to enter your lungs. With VitaminD, that phase of the flu is gone. I dont supplement regularly, and I start taking it the day I feel I am going down with the flu. No point recommending it because you will be seen as someone wh…

Doesnt this basically explain the real reason for why flu is worse in winter. Less sun exposure in general.

I always wondered this too. I didn't think it had anything to do with the temperature of the air... how does that make sense?
