2000 IU of vitamin D- doctors trained that it was too much, but it is often too little

Most doctors limit their vitamin D prescriptions to 2,000 IU

The doctors training (incorrectly) told them that any more than 2,000 IU could be toxic

At least one Randomize Controlled Trial had to stop the 2,000 IU leg

because 2000 IU was not providing the healthful outcome that the 4,000 IU leg provided.
