Ok so here's my question does anyone inject their prey items with liquid vitamin?

Ok so here's my thought process on this... A few years ago I used to keep a few different types of snakes and lizards and have recently gotten back into the hobby and will be breedig balls next season. Anyway, back when I kept my snakes last time I would inject a liquid vitamin under the skin of my rodents prior to feeding.

Now don't get me wrong I'm not suggesting that every animal I own should be dosed with vitamins but my thought was that it may be beneficial to dose a snake that is I'll or injured in some way to help boost their system so they can heal faster. Also I considered injecting the feeders of my hatchlings to ensure that they get a little boost early on. Likewise, I would consider doing this for females preovulation or if they were gravid to assist in the entire egg devolopment process. And lastly, if an animal had been off feed for several months my thought was it could be beneficial to give them some extra vitamin when they start feeding again.

If it were something they didn't need I would think they would simply pass the unabridged or unneeded amount.

Just wondering if anyone out there has or does do this?
