Currently I am taking a multivitamin, fish oil, and I recently added vitamin D supplements (D3 to be specific).
My current routine is take each of the three (along with some unrelated medication in pill form) after I eat breakfast each day.
The addition of the Vitamin D supplement has led me to wonder if taking all of these at the same time of the day is the best idea, or if it would be better to take them separately. For example, my multivitamin already has 400 IU of Vitamin D in it, and then I am adding another 1000 IU in the D3 pill.
Is my body capable of ingesting this much of the vitamin (along with everything else in the multivitamin) at the same time, or will some of it be wasted and end up being excreted? Would it be better to take one at morning and one at night?
