I would think it's useless and probably just a gimmick. However, the Benepac is the probiotics I've been telling you about. I give it to snakes after deworming, antibiotics, and to newborns to establish/reestablish healthy gut flora. It's not something you want to use routinely but it probably wouldn't hurt to give a little to your snakes once a year or so after a long fast, before and/or after brumating. .
