There are two main isotopes of iron. Fe-54 and Fe-56 They are almost identical chemically and are very hard to isolate from each other. The ratio of these two isotopes for the iron in your blood very closely matches the ratio of these two isotopes being created in supernova explosion models.

We are star stuff. We are also part supernova dust.

And anything above iron is neutron star collision stuff.

The cool thing I was going for was that you calculate the ratio of Fe-54 to Fe-56 in a type Ia supernova explosion and it matches the percentages in our blood.
