In this particular case, humans are quite different than animals and in fact probably need even more.
There are only something like 3 mammal species on the planet that can't make their own vitamin c. Humans and the upper primates, Guinea pigs, fruit bats, and one or two more CANNOT make their own, and get what they need from their diet.
So the amount a goat has in it's blood is what it's OWN BODY made. And it's body isn't gonna make it if it doesn't need it.
And I know about polar bear livers. The fact that a polar bear has that much vitamin A in it's body at all should tell you something about the importance of vitamin A!
Feel free to do some research before you come back and argue.

I'll freely admit to my sketchy medical knowledge, and wouldn't be a bit surprised to be wrong.
My point was to be cautious of thinking that if a little vitamin C is good, a lot must be better. Vitamin A is important, too, as proved by the amount stored in polar bear livers. If we take that at face value and consume a huge amount of A, toxic results follow.
