D3, 5000-8000 IU day
and sun exposure
are insufficient to raise vitamin d
levels many physicians recommend a daily dose of 5, 000-8, 000 iu of vitamin d3 .
Once 25 hydroxy vitamin d levels reach 60 - 80, the daily dose (5, 000-8, 000) is usually cut in half and the patient followed to ensure the new dose is able to maintain therapeutic vitamin d levels.
