It's worth noting that vitamin D has a lot of high-confidence but low-effect results going for it, including a lot of strong meta-analysis over many health outcomes. What I mean by this is that it usually seems to conclusively either do something beneficial, but minor, almost nothing in the case of many studies, and in the case of some others, something very beneficial (as we've seen a few of in relation to covid rec…

> and almost no risks This isn't true--especially for Vitamin D. We have several doctors at this point who deal with cases where too much Vitamin D causes Calcium uptake issues and affects cognition and heart function. Vitamin D is NOT something like Vitamin C. Your body easily dumps excessive Vitamin C so you can take fairly massive doses with no real ill effects. Your body has a much tougher time excreting Vitamin…

Too much Vitamin D without sufficient Vitamin K can lead to high levels of serum calcium that are not absorbed into the bones. One function of Vitamin K is to shuttle calcium into the bones. You can often purchase combined Vitamin D and Vitamin K supplements to avoid those issues.

Worth noting that the above mostly talks above Vitamin D specifically, not multivitamins. D is the only one you do not naturally get from food (ignoring fortified food), and it also as mentioned above one of the cheaper ones. Multivitamins are far more expensive in general.

Mushrooms? Salmon? Liver? Eggs? All of these have vit D without being fortified (mushrooms being a bit debatable as to if its fortified) And its a little misleading not to talk about sunlight - technically that's not a food, but you were kind of implying you couldn't get it from the natural environment.

Vitamin D2 + D3 per 100g portion of mushrooms, according to this website from the USDA Agricultural Research Service (https://fdc.nal.usda.gov/)

- Mushrooms, raw: 0.2 µg (7 IU)

- Mushrooms, Chanterelle, raw: 5.3 µg (212 IU)

- Mushrooms, enoki, raw: 0.7 µg (29 IU)

- Mushrooms, maitake, raw: 28.1 µg (1123 IU)

- Mushrooms, morel, raw: 5.1 µg (206 IU)

- Mushrooms, oyster, raw: 0.7 µg (5 IU)

- Mushrooms, portabella, raw: 0.3 µg (10 IU)

- Mushrooms, shiitake, raw: 0.4 µg (18 IU)

- Mushrooms, white, raw: 0.2 µg (7 IU)

As you can see, there are many types of mushrooms and most of them do not have much vitamin D. Some do, but unless you are a mushroom nerd you are getting the wrong kind.

Young adult daily recommended dose = 1000 IU

Or just get some sunshine! It's likely there are other benefits, besides just the vitamin D.

Well I mean, in Australia, that leads to skin cancer, so I'll just take some tablets thanks!

Vitamin D taken via pill is not the same an that manufactured by sunlight. The pill form has side effects like causing too much absorption of calcium in the intestines, which leads to other problems. This is something that doesn't happen from sunlight.

almost no risks or real costs I worry a little about risk compensation, or whatever the equivalent is for diet. That is to say, if I feel like I'm all set on vitamins & minerals via pills, maybe I don't need to try so hard to eat my fruits & vegetables anymore...

"Risk compensation", to use your term, is a perfectly rational way to deal with these issues!

Funny -- I was just digesting a competing study released recently[0] which showed little-to-no benefit from vitamin D, Omega 3 fatty acids, and exercise (either alone or in combinations). That study used 5X the daily vitamin D as this one. So I guess the jury's still out and I may choose to continue to err on the side of supplementing vitamin D.

Correct. Perhaps even more important than vitamin D is nitric oxide. The summarised advice is to avoid the sun when it is high in the sky (noon-ish), get some sun in the mornings/evenings, and supplement vitamin D. This ensures good levels of vitamin D and nitric oxide while reducing skin cancer risk.

Interestingly, Oxidative stress is considered to the main cause of COVID-19 infection severity, according to Dr. Roger Seheult in his bio-chemistry analysis of SARS-CoV-2 in human body. He also explained why Vitamin D could help reduce the mortality of COVID-19 due to Vitamin's ability to slow down oxidative stress.[2]

Dr. Seheult is the main lecturer of his popular YouTube channel MedCram[3] and is a board certified physician in Internal Medicine, Pulmonary Diseases, Critical Care Medicine and Sleep Medicine.

We could fortify beer and Coca Cola with it. While it’ll be on the label, I bet 9/10 people can’t rhyme off what is fortified. (Around here, it’s salt, milk, flour and cereals that get fortified). Dunno where fluoride fits, but that too.

You belong to an interesting language isolate with whoever wrote this article:

SUNNY VALLI CRAG

I was puzzled by your phrase "can't rhyme off". Google returns very few instances that are not related to spontaneous spoken word poetry (which is likely an example of convergent evolution). After poking around a bit, it seemed as though I had heard a similar phrase before "try (to|and) rhyme off" in which 'rhyme' is synonymous with 'to list' as well

Best wishes for yourself, your friends and your family during these uncertain times!

I was pretty amazed to Discover that Spirit Airlines is doing round trip flights for $75 to Orlando from my local airport. If you’re in the Midwest in a midsized city that’s cold and dreary in winter there’s a good chance you can find a similar deal.

I know different people have different risk tolerances, but there’s no way I would get on a plane during a pandemic if I don’t have to.

An airplane is probably a safer place to be than your local grocery store right now.

For reference: The level of toxicity listed in your link is 60,000IU per day. Fauci said he takes 10,000IU per day. The bottle I purchased recommends 2,000IU per day. Get your blood work done people.

There's an expert that specializes in vitamin D toxicity cases and regularly posts here. She sees cases at less than the 10000IU daily dose Fauci takes. I would be hesitant to go above 4000IU daily without monitoring blood levels every six months or so. Its winter here in Canada, I'm taking 3000IU per day. I drop that to 1000IU in the summer. I'm not a doctor, not recommending you do the same. Just sharing.

Obvious warning but there's a lot of name dropping and I'm not sure what leads people to think Fauci 1) takes 10kUI or 6kUI per day 2) that it's the right dose for them 3) that they can make conclusions on what to do with their health based on a forum.

Get your blood checked, get recommendation from a doctor... before supercharging your blood with calcium & other fun stuff...
