Can you point to links on consequences of overconsumption? I wasn't aware of any major downsides to consuming vitamin D in this dosage range.

It seems like one issue is restless leg syndrome, but with an issue like that, you can just shoot high anad lower your dosage if you discover that to be an issue.

The unfortunate problem in the US is that those suffering most severely from many of the symptoms of vitamin D deficiency are often unable to obtain healthcare, so a lot of people out there are left to make guesses their own healthcare on issues like this. Getting vitamin D serum levels tested is a luxury reserved for those in first world countries.

I'm very skeptical of anything on a technical field like nutrition coming from a general news source like CNN. Most of what they report about fields I'm an expert in is straightforwardly incorrect, so I can only guess that they're equally incorrect about nutrition.

Even if they're correct, it's hard to find any useful information here. They mention three numbers: 150,000 IU, 50,000 IU, and 4,000 IU. The 150,000 IU and 50,000 IU examples exhibited serious symptoms, but the number mentioned a few posts up is 10,000 IU. The 4,000 IU number is mentioned in the sentence, "A 2017 study found 3% of Americans took more than the tolerable upper limit of 4,000 IU daily for adults, thus putting themselves at risk for toxicity." But there's no discussion of what symptoms would be experienced at this level of toxicity.

As I said above, if it's just restless legs, it doesn't seem unreasonable to try the dose (10,000 IU) and lower it if you experience restless legs. Obviously it's better to get a blood test, but as I said before, not everyone has access to that kind of healthcare.
