For horses with a tendency to get muscle craps on trail
Highly recommended to me by FEI Endurance riders, I did not notice a difference in my horse when using this. Perhaps it is more useful for horses who have muscle cramp issues, and/or are working in very hilly terrain? We ride on relatively flat, fast terrain and it didn't help NOR hinder.
