I believe it is cobalt as well, humans need it through vitamin b12 and helps produce red blood cells.
 
And the answer is...

1. I am part of a vitamin humans need
2. I am an element in seawater
3. Rearranging my name, and leaving off a letter, can spell "bloat"

What am I"

Cobalt!

as some folks correctly identified!

Happy Reefing :)
