Yep. And where does taurine come from, I wonder, that it
is not present in tuna? Does it come from hair and eyeballs
and bones and toenails and stuff?

Not hair, nor eyeballs, nor toenails.

IIRC it's most concentrated in the central nervous system, heart and
striate muscle.


Thanks Steve. I was just looking at a site about that. It comes
from animals, just not all animals.
