Thanks for the response. I'm curious what your wife thinks about this article [0], mentioned elsewhere in this discussion. It makes the case that the current RDA for Vitamin D is based on a statistical error, and that the recommended dose should be closer to 8000 IU for young adults.

- graeme 6y agoNot OP, but with vitamin D the dosage is actually something you can figure out empirically by testing vitamin D levels and taking supplements. No one who talks about supplementation seems to think a level of 8000 over a long period is necessary to obtain adequate levels. I think by the same token the recommended supplement level of 600 IU is inadequate to reach a sufficient level. But the paper in question didn’t test their result empirically.
- devaboone 6y agoCorrect. It's fairly easy to know whether the dosage you are taking is working, since you can check levels. 8000 units is a really high dose, one that I have never had to give. The article suggests that 98% of people require that much to get to normal levels, which is almost laughable.
