I frankly don't think that's a very good idea. Yes, in the wild snakes eat other snakes, but not only do they eat the skin, but the entire liquid filled nutritious snake that goes with it. And for the life of me, I've never heard of a case where a wild snake ate an empty shed.
It'd kind of be like a human eating their fingernail clippings for better fingernails. After cats groom their fur, they hack out hairballs, they don't digest it. There's a pretty scary risk of impaction I'd think.
I know there have been a few discussions on vitamins. If you're looking for different forms of nutrition, maybe you could forum search for those?
