Best joint supplement to feed?

Just as an aside, Cosequin is comprised of nothing more than glucosamine, chondriotin and manganese. It is an oral supplement for joint health.

Have you ever heard on Platinum? There is a supplement called Platinum Performance CJ and it works wonders! Every old and arthritic horse that has come through the barn I work at gets put on it, and it seems like just a few days later they're acting like young horses again! It's amazing stuff, pricey($140 for 10lbs from their website), but is very much worth it if you want to see your horse do a 360! Seriously, I can't say enough good things about this product!
