Performance horses, such as those competing in endurance, racing, or three-day eventing, lose significant electrolytes through sweat during intense exercise. Replacing these minerals is critical to prevent dehydration, muscle fatigue, and tying-up. Our editorial team compared leading electrolyte supplements to help you choose the right one for your equine athlete.

We focused on products with balanced sodium, potassium, calcium, and magnesium levels, avoiding excessive sugar or fillers that could upset a horse’s digestive system. Each pick is evaluated for palatability, ingredient transparency, and suitability for horses in heavy training.
