horsecrazy, I got a supplement from my vet that is same in amounts of "good things" as Smartpack, yet much cheaper (they get it directly from the supplier). I'll check the name tonight when I get home. Vet swears by it, and I've been using it for couple months so far (after my horse was diagnosed with pretty bad case of arthritis).
