Safe To Continue: Ideal levels of vitamin d and B12 are 60 - 80 and 200 - 800, respectively. Talk to your doctor about increasing your vitamin d3 daily dose to 5, 000-8, 000 iu per day. After vitamin d is in the normal range we usually cut the daily dose in half and follow the patient to ensure the new dose is able to maintain therapeutic vitamin d levels.
