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 Farnam Apple Elite Electrolyte Pellets are designed to replace essential minerals lost by horses through sweat during exercise, harsh weather, and stressful conditions. It features a balanced formula containing sodium, potassium, calcium, and magnesium, which are crucial for maintaining fluid balance, proper digestion, muscle function, and recovery.

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 product comes with a 100% satisfaction guarantee and is available in a 7.5 lb. container, providing up to a 40-day supply.

The Finish Line Horse Products Apple A Day is a 30-pound powder supplement designed to support horse hydration and replenish electrolytes. It comes in an apple flavor, which is likely to be appealing to horses and can aid in increased appetite and water consumption. This supplement is gluten-free, making it a safe choice for horses with dietary restrictions.

Finish Line has been a reputable brand in the equestrian community since it first appeared on the market in 2008. However, the best sellers rank of #122,959 in Pet Supplies suggests that it may not be the most popular choice available. One of the potential drawbacks is that it comes in a large, 30-pound size, which, while economical, might be cumbersome for some users to handle and store. The powder form can be a bit messy to measure and mix, compared to pre-measured doses or liquid supplements.

Finish Line's Apple A Day is a solid choice for horse owners looking to maintain their horse's electrolyte balance and hydration, especially if they prefer a flavored option.
