Liver is also where the body stores and processes toxins - do you actually like the stuff? I have always heard eat it in moderation. You could try dessicated liver tablets, but the smell alone was enough to change my mind.
asimmer is right. the liver tabs are the way to go. The fat and connective tissue has been removed, and it's a much more concentrated version of all of the nutrients found in just a hunk of liver.
