Star Stuff

Explanation:

All matter heavier than hydrogen in your body was produced in stars. The elements lighter than iron were produced by the process of fusion, the heaver elements we produced by an exploding star called a Super Nova.

Of course the majority of your body is water #H_2O#, the hydrogen in water was present from the Big Bang, the oxygen is "star stuff".
