When I was working as a nurse practitioner, if I knew the person’s vitamin D level, I would advise the person to take 1000 IUs for every 10 ng/ml I wanted to raise his vitamin D level. For example, if he had a level of 40ng/ml, I would advise him to take 2000 IU/day to get him up to a level of about 60ng/ml. This was a simple formula that worked pretty well.
