Racing, eventing, show jumping, pulling, and dressage, take a toll on horses physically and emotionally. On top of asking them to perform at the top of their game, we also play havoc on their digestive systems with high grain diets.
When you combine our husbandry practices and breeding for speed and athleticism, it is no wonder horses occasionally act as if they have lost their minds. Fortunately, we may be able to soothe troubled waters with calming supplements and consistent training.
We reviewed 10 products, trying to determine which we could recommend as the best calming supplement for horses. We analyzed safety and quality of ingredients, presence of potentially banned substances, effectiveness, and overall customer satisfaction.
