Probably why we (humans) don't eat other carnivores. Herbivore livers don't get nearly that concentrated.
True. But there is a difference between animal and vegetable sources. According to http://www.dietitia
n.com/vitamina. :html
"What is known about Vitamin A at this time is that there are animal sources (retinol) and vegetable sources (carotenes) in foods. Animal sources are about six times more potent than vegetable sources and can be toxic if taken in excess. Because of this, Vitamin A supplements are restricted to carotenes and under limited to under 25,000 IU per pill. One ounce of polar bear liver contains enough Vitamin A (retinol) to kill a person!"
