When that came out a few years ago [1], I began getting my vitamin D tested through my doctor and slowly ramped up my dosage. It went from 28 ng/mL (70nmol/L) [2] to 32-35 ng/mL (80-87.5 nmol.L). In my own physiology, this required 4,000 IU (100 mcg) daily, orally. 2,000 IU was not quite enough. I'm going to add another 2,000 IU daily to see if I can reach the recommended 100 nmol/L from the OP.
