synthetic vitamin A (the mass produced variety; animal livers are not an efficient way to make it on a large scale) is just as bad, and both types are known to cause congenital birth defects if taken in high enough dosesOnly animal based vitamin A (straight up retinol, I think, there is a lot under the "A" umbrella) is super toxic like that. One ounce of polar bear liver and you might be dead.
