I have been taking vitamin regularly since 2009. My levels have generally been about 32ng. I upped my dosage and achieved 54ng. Is there any indication of what dosage is required to maintain this level?

    The dosage required is about 5000iu a day for a 150lb person. It could end up more or less than that if you are smaller, taller or overweight.
