This sounds familiar. Just two weeks ago, I was speaking to my vet about our 21-year mare getting a little stiff. I asked her about joint supplements and she stated that most don't do much good. However, she did like Platinum Performance, and said out of all of them it was effective if we wanted to supplement. Ultimately, we decided on a low dose of bute a day to see if it helps. I voiced my concern for stomach issues, and we're doing this as a trial run for a few weeks. Rena feels pretty good, though. Got a little more pep in her step.
