Vitamin A is a pretty significant one. It’s not soluble in water, so it bioaccumulates. Polar bears are predators that eat predators (seals) that eat creatures that eat autotrophs that are very vitamin A rich (alae, phytoplankton, etc.)
Because of that, 0.1 grams of polar bear liver has 100% of your daily recommended vitamin A, and as little as half a kilogram has enough to kill you =)
