actually you lose nutrients anytime you freeze anything. As a matter of fact, you lose pretty much all your B vitamins. This is why I have to sprinkle vitamins on my ig's salad everyday.
I guess if you are going the F/T method, you should already be dusting them with vitamins. Otherwise I'm guessing there are some unhealthy snakes out there.
Why does everyone attack people who feed live? Yes it can be more dangerous for the snake, but also better nutrients. I can see the argument both sides but all y'all do is attack someone who questions it. I guess if the snake doesn't take F/T they should just starve to death so they don't get hurt?
