    Rated 5 out of 5 by from Great supplement! I'm very happy that I put my mare on this a few months ago. It has helped keep her loose & moving great during this terrible winter with limited turnout & freezing temperatures

    Rated 5 out of 5 by from GOOD JOINT SUPPLEMENT Have been using Smarkpak joint supplements for quite awhile on two horses. The only reason I didn't go 5 stars the whole way around is that I thought I would try the powder instead of the pellets. My horse likes the pellets better. Overall the Smark pak joint supplements are great products!! Used on a 23 YO jumper and and 6 YO jumper
