Pre-op Vitamins...D/D3

Silly question but I am already on B-12, Calcium citrate, and of course a multivitamin. My dietician directed me to go ahead and start taking a Vit D as well, 2000 IU daily. I found a tiny chewable, strawberry banana flavored, which is really yummy! But after I looked at the bottle it stated D3. If I am thinking correctly this is the same thing, right?

There are two types of vitamin D, D2 and D3.  D2 must be converted to D3 in the body and it takes a lot of D2 to make a little D3.  Therefore taking D3 in the first place works better.  That's what I would take.
