10 Best Horse Electrolyte Supplements 2026 in the United States

The REDMOND Rock Crushed Loose Mineral Salt Electrolyte Supplement is a natural and versatile option for maintaining your horse’s health. One of its standout strengths is the composition of over 60 trace minerals and electrolytes, which are crucial for preventing mineral deficiencies and dehydration. The supplement is free from fillers, grains, sweeteners, and artificial colors or flavors, making it a pure and natural option for your horse. The form of the supplement is a powder, labeled as 'Crushed Rock,' which you can easily mix with feed or offer free choice, adding convenience to its use.

With a weight of 25 pounds, this product is quite substantial, potentially lasting a good amount of time depending on use. However, the form and flavor may be less appealing to some horses, especially those that are picky eaters. The well-regarded Redmond brand adds to its credibility. It’s also noteworthy that the product provides clear usage instructions to help you integrate it into your horse’s diet seamlessly.

On the downside, some users might find the product dimensions (2 x 2 x 2 inches) and weight cumbersome to handle or store. This makes it an excellent choice for horse owners looking for a natural, mineral-rich electrolyte supplement, especially if the horse is not selective about the flavor and form.

The product is in pellet form and has an appealing apple flavor, making it suitable for daily use, even for picky eaters or horses that typically avoid powdered supplements. The ease of use is highlighted by the enclosed scoop and clear feeding directions based on the intensity of the horse's activity, ranging from maintenance to heavy sweating conditions.

The pellets can also be used proactively before exercise or travel to minimize electrolyte loss. Farnam, the brand behind this product, is well-regarded in the pet supplies industry, adding a level of trust and reliability.

The apple flavor is a nice touch to encourage horses to accept the supplement, though flavor preferences can vary among individual horses.

This powder form is easy to mix with feed or give directly, offering flexibility in how you manage your horse's hydration, especially before exercise, travel, or stressful conditions. Farnam is a reputable brand in equine care, and this product enjoys high customer ratings, reflecting consistent satisfaction. One thing to keep in mind is that as a powder, it requires mixing each time, which might be less convenient than ready-to-use liquid supplements. However, this format allows for accurate dosing and storage.
