You know I use a vitamin d supplement because I'm not a big outdoors guy and I livein the northern USA and I was deficient at my last annual inspection. That said why does HN seem to have a vitamin D story everyday? It's not a magic pill. If you have deficient levels you should do something about it, but it's not a cure all.

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.
At the grocery store I can bolt at a moment’s notice if I see anything sketchy happening. No can do on an airplane. There could be a guy sitting next to me and coughing all over me for hours.

#83Why does it have to be supplementation? Nutrition science is mostly unreliable because it is difficult to study, is very limited and progress is slow. The supplementation industry capitalizes on this ill-reported junk science. For many years, vitamin D2 was sold as supplementation. Now it is well-known that D2 is not bioavailable to humans. Similarly, it is well-known now that even D3 is mostly useless without K2. No…
I read that there is 15 UI of vitamin D in a steak. You need 25 or 100 times that per day. It’s more likely that humans evolved to get their vitamin D from sunlight (although we also know that introduces cancer risk) than eating a whole cow every day. It seems like you’re trying to make the facts fit your preferred narrative re. meat consumption.
>I read that there is 15 UI of vitamin D in a steak. You need 25 or 100 times that per day.
And how do you that for a fact? It's nutrition science. It's not reliable. These numbers of how much we need has been changing for as long as I can remember.
>It seems much more likely that humans evolved to get their vitamin D from sunlight
Humans have lived in Northen Europe for at least 10,000 years. They didn't take any supplements and there no evidence that shows any vitamin D deficiency in those populations.

#84It'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…
> exciting supplement
I've never taken one in my life and have excellent vitamin D levels.
Most people call it going outside you desk jockey nerds.

Humans in Northern Europe have adapted to those conditions with very light skin that maximizes sunlight exposure.

The changing numbers are why I gave such a wide range. Regardless of who you believe, it’s completely impractical to get the vitamin D you need from meat. It’s not even in the right order of magnitude. What is your proposed required daily value of vitamin D? If you’re going to go around claiming it’s possible to get your needed vitamin D from foods, you ought to have done some math to back up this claim.

> 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…
It’s not vitamin D that needs to be excreting but calcium. That’s why some supplements include vitamin K2, allegedly to absorb calcium into bones.

The only relevant math I need is that humans have done fine with animal fats for thousands of years. The value I need is what I can get naturally.
And BTW, I have dark skin, I live in one of the Northest parts of the world humans live, haven't taken vitamin D supplements in years and my vitamin D levels have been great (upper middle of whatever acceptable range they use) when I got tested several times over the past years. I don't even care anymore. I will continue to eat what humans are supposed to eat and I'll be fine.
Even if your numbers are not good, you should not be eating these chemicals in isolation. We don't need nutrients, we need food.
Nutrient-nutrient interaction is very difficult to study, but it has been found to be crucial every time they've managed to do it.

Perhaps you’re eating some food that has been supplemented with vitamin D. For example, one cup of milk fortified with vitamin D might have 100 UI (as much as six steaks).

And even in Northern Europe, people were outside all the time. Nowadays we sit in the dark offices in the artificial lighting.

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…
