The IOM's suggested RDI is clearly far too low. Those familiar with your work and that of other Vitamin D researchers will know that 600 IU per day is not nearly enough to overcome widespread deficiency. They are to be congratulated for raising the suggested upper limit to 4000 IU, though. This is a reasonable intake and is what I have moved up to (from 2000) since the report.
