Interesting report. Two concerning bits though:

No attempt was made to distinguish between vitamin D2 and D3 because there was not always a distinction in the literature. However, vitamin D2 is less effective at raising serum 25(OH)D concentrations than is vitamin D3 (13).

And that the group sizes (“n” values) top out in just one at 1653. The rest are usually under 20.

Which doesn’t matter in the slightest as my post was to simply make the OP aware that too much can be harmful.

Your post simply raises the bar on how much is too much, but doesn’t change the underlying point I was trying to make.

Thank you for posting that report!
