> Taking 10s of thousands of IUs every day for years is probably a bad idea for anyone who isn’t regularly checking their Vitamin D levels.

This extreme is obviously bad but if you spend most of your time indoors and you're located somewhere that doesn't get much sun without government fortifying your food with vit D (like some Scandi countries do), I don't see the harm in taking somewhere around low 1000sIU per day.

"The average content of vitamin D 3 found in wild caught salmon was 988 ± 524 (mean ± SEM) IU of vitamin D 3 /3.5 oz which is a typical amount that is served for dinner (Table) In contrast, farmed salmon had approximately 25% of the vitamin D content present in the flesh of wild salmon"

And everyone knows that a fish meal that size doesn't satisfy all the way to bed time.

So you can imagine a hunter gatherer running around eating a ton of fish, berries etc. and how many IU's that would be
