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.

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.
