I am looking to start my horses on a joint supplement. One horse is a 15 y/o OTTB who I ride 5-7 days a week including trail riding and jumping maybe 2-4 times a month. She occassionally is stiff (rare) but is otherwise sound and doesnt seem to have joint issues but I want to make sure she is feeling her best and prevent anything. My other horse is about 20 and retired. He has arthritis in his hocks and I ride him 1-2 times a week and do pretty much only walking on the trail with him.
What should I feed them for a joint supplement? Do I want to buy something with MSM or glucosamine and chondroitin or should I feed them both?
Thanks for your advice.
