Are you receiving this IV because you are on prednisone or for some other reason?

I was told to take one vitamin for one thing and another vitamin for another thing. My labs would show a lower level of this or that.. Most of the time it seemed like it was related to a prednisone side effect but it could be age or diet related. The treatments were over-the-counter things so I ended up taking a multivitamin with minerals.

Now whenever a doctor asks me if I'm getting enough this or that ,,, I just say yes to everything. I don't know if I need everything or not but it doesn't seem to cause any problems.
