Show legal joint supplement?
I've talked to several vendors at a horse show last week about joint supplements. I finally found one that sounded promising but then the salesman told me it wasn't show legal because it had "Devils claw" in it ( I had no idea! ) Now I am worried that whenever I find a good one it might have some type of herb in it that could possibly be illegal in the show ring. Can somebody please tell me where I can find a list of ingredients that are banned from the show ring? Thank you!
