Given the half life of Vitamin D is about 3 weeks how much Vitamin D do you think you need to store before the end of September in order to reach the end of February remaining above 50ng 125nmol/l?

Bear in mind this is the threshold below which calcitriol can not operate at Vmax because it is limited by lack of substrate.

I could argue that the Inuit don't supplement with anything nor do they get enough sunlight to cause any vitamin D production yet are as healthy as anybody all year round. Hitchinson, I don't want to contradict you. I changed my mind, that's all.

I thought the inuit got a load of Vit D3 from eating seal/fish livers.

They do. Their traditional diet has always included lots of oily fish. That's why their skin still has its color.

but we do know the Inuit and other traditional cultures at that latitude consumed large amounts of vitamin D from nutrient-rich animal foods like fatty fish and seal meat and I would guess seal oil will also be good vitamin D3 sources. I suspect you don't eat seal meat or seal oil daily so I am concerned that you may not be able to account for adequate D3 sources between October and March.

I could argue that they don't get any vitamin D from animal source during a caribou year. Don't worry about me. I'm doing just fine.

Maybe. But what happened when they ate caribou?

Unless it was a caribou year. In which case they didn't eat any fish.

Can you provide a link to confirm that they wouldn't have taken dried fish on Caribou hunts.
How can you be sure they didn't use seal oil to cook their meat?
Seal oil will be a source of vitamin d.

Seal oil will be a source of vitamin d.

Why would they carry fish if they hunted caribou? Conversely, why would they keep caribou if they caught fish? Yet again, why would they keep fish or caribou if they hunted seal? The Inuit don't have any nutritional theory. They eat what they hunt and that's it.

-edit- I get my information on the Inuit the same place you get yours. From Stefansson's accounts.
