I take a women multi which has 800iu of vitamin d but then I also take calcium with vitamin d and that has 400iu and take 2 so that is 1600vitamin d daily is that too much? I just realized that. The calcium is 600 in each of the calcium so that is 1200mg and my vitamin has 450mg elemental in addition.So that is 1650mg. I thought you could get too much d. Is that wrong?
