Need more D3,?B12 IM: It will take several weeks to raise d levels much but 1000 iu is not nearly enough- people need 5-8000 iu/day to achieve optimal levels of 50-80. I advise taking 10, 000 iu/day for 3 months ; then recheck levels- see http://bit.Ly/1gnxnk0 it's possible you can't absorb B12 in which case no oral dose would help. I would give 1000 mcg im 2-3x/week for a month then see if oral forms can maintain it.
