They recommend 4,000 IUs of vitamin D as the maximum safe dose, not because higher doses were found to be less helpful but because 4,000 was the most helpful and also the highest amount they actually tested. It is possible (but untested) that 6,000 and 8,000 IUs could have been even better.
However, it does appear that at 16 weeks both the groups getting 2,000 and 4,000 IUs of vitamin D leveled out at the same blood serum level of vitamin D.

- ghaff 9y ago4,000 IUs isn't really an especially high dose. Standard Vitamin D supplements that many doctors commonly recommend (especially in places where people don't get a lot of sun for much of the year) are 2,000.
- buttcoinslol 9y agoI take 4000 IUs a day on the 45th parallel from late September to April, 2000 IUs during the summer. More than one doctor has OKed this dose. I was at 8-10 ng/ml a few years ago and now I take Vitamin D very seriously.
