When you warm up milk do you lose the vitamins or calories or any of the nutritional value?!

Answers: If you just warm it like you stated then no, no loss of vitamins or any other nutritional component. If you heat it for a long time or boil it, you surely will lose some of the heat labile vitamins. You will also begin to denature the casein but that's not necessarily a bad thing.

If you heat it in the microwave you will lose nutrients. Mothers who are breast feeding have to warm their milk with bottle warms or by boiling it to keep all the good stuff in it.
You don't loose anything really important unless you boil it for a long time, and even then the worse that will happen is that you'll degrade a few proteins and perhaps the vitamin D as well. All the calcium and sugar will still be there.
