I haven't heard of that, but did a search on it and it looks much the same as what I'm using on Maddie, which is Life for Teeth and Brush away.

I have been using it about 6 weeks now and plan to continue. I can't say that it's been great, because Maddie didn't have any plaque or tartar when I started. I just started using this to hopefully keep them that way and hopefully not have to have any teeth cleanings done by the vet.
