Horses and Electrolytes, The Proper Balance

NutriBit article, Horse Electrolytes

by David Anderson, The NutriBit Company

You can lead a horse to the salt block but you can’t make him lick. This statement is as true as the old maxim concerning making a horse drink water. In fact, the old salt block may not be licked frequently enough to provide adequate consumption for your horse’s salt and mineral needs. Salt as well as water is at the top of the list for healthy animals. Why are salt and water so important? The answer to that question is easy. A horse’s body is made up of approximately 60% liquid. Salt and water are the major components of that liquid- change the natural balance in that equation for prolonged periods of time and trouble is generally just around the corner.

Basic Make-Up of Internal Liquid The liquids found stored in a horse’s body are divided into two areas: extra cellular and intracellular. Extra cellular is the liquid found outside the cell such as plasma, brain fluids, stomach fluids, etc. This accounts for approximately 33% of the total fluid in a horse. The other 67% is intercellular or liquid found within the structure of the cell. Some of the major components of the cells are: sodium (NA), chloride (Cl), potassium (K), calcium (Ca2), and magnesium (Mg2). These components are what are called electrolytes.

What are Electrolytes?

Electrolytes, at the primal level, are salts that divide into separate ions when they are dissolved in water. They are essential to basic muscle and nerve utility and to most of the other physiological processes. As mentioned above in the cell structure, basic electrolytes consist of: potassium, calcium, sodium, chloride, and magnesium.

Consequences of Lack of Electrolytes A horse’s body is constantly trying to correctly balance the electrolyte amounts in the system. In fact, if a horse receives too many electrolytes the horse’s system will flush the excess out through urine or sweat. If this balance is deficient over time, the consequences can cause bodily dysfunction. Problems can develop in the brain, resulting in unclear thinking. Also potential areas for problems are the digestive system, the muscles, and even the heart.

Activities That Lower Electrolytes Horses can lose large amounts of liquid in extreme exercise situations such as endurance rides, long trial rides, heavy work-outs , and competitive events. Depending upon the activity and the air temperature, a horse can lose 2 ' gallons (or more) per hour of liquid. That is a ton of liquid that will eventually need to be replaced. Horses have a tendency to lose more electrolytes in the sweating process than humans. During work-outs the biggest electrolyte losers are sodium, chloride, and potassium. It is during these electrolyte draining activities that you may choose to supplement your horse’s electrolyte intake. Different methods and types of supplements are available from salt and mineral blocks to pastes and liquids.

Don’t Forget the Water While replacing electrolytes, don’t forget to provide the water requirements for your horse. As a general rule a non-active horse needs about a gallon per 100 pounds of his weight per day. An active horse can required 2 to 4 times that amount. A method of adding liquid to your horse’s diet is to soak or spray your hay with water before feeding. Dry hay can consume water that is necessary for the digestive system.

NutriBit

The majority of electrolyte loss takes place in the early stages of a work-out. During events like endurance rides or trial rides it is difficult to administer electrolytes and supplements during the ride. Now there is a new product called NutriBit that allows the rider to give electrolytes and vitamins to the horse while in the saddle. The secret of this device is found in the rein and bit system. With a pouch located on the rein, to hold liquid nutrients, the rider squeezes the pouch which pushes the fluid down the rein through an enclosed hose and into the bit. The bit has been manufactured to allow the nutrients to enter and exit by dropping on top of the horse’s tongue.

The NutriBit system also has an option for an owner or caretaker to administer liquid nutrients while on the ground. The system has a quick release mechanism that changes quickly from an in-the-saddle system to an on the ground syringe-to-bit operation. Whatever method(s) you choose for supplementing your horse’s electrolyte needs be sure you don’t give your horse the responsibility of giving himself the proper amounts of electrolytes or other vitamins and minerals, by means of a salt or mineral block. Take that responsibility yourself. Written by David Anderson david@NutriBit.com

Key Article Takeaways
  • Per David Anderson, NutriBit Company: a horse's body is approximately 60% liquid—electrolyte balance is critical.
  • Salt block licks rarely deliver enough sodium and minerals; supplemental electrolytes fill the gap.
  • Sodium, chloride, potassium, calcium, and magnesium are the major equine electrolytes.
  • Extra-cellular liquid (plasma, brain, stomach) is 33%; intracellular is 67%.
  • Electrolytes are essential to basic muscle and nerve function—deficiency shows up everywhere.
Questions readers commonly ask:
Why isn't a salt block enough?

Per David Anderson: most horses don't lick salt blocks frequently enough to meet their daily sodium and mineral needs—especially in heat, during exercise, or while lactating. Loose salt or formulated electrolyte products deliver more reliably than expecting the horse to dose himself from a block.

What are the major electrolytes a horse needs?

Per David Anderson: sodium (Na), chloride (Cl), potassium (K), calcium (Ca²⁺), and magnesium (Mg²⁺). Each plays specific roles in muscle contraction, nerve signaling, and fluid balance. Imbalance in any one of them affects performance and health.

When does a horse need supplemental electrolytes?

Per David Anderson: during heavy work in heat, multi-day hauls, lactation, intense competition seasons, and recovery from illness. Maintenance supplementation in moderate weather is usually achievable from forage plus salt access; performance situations demand more.

Can I over-supplement electrolytes?

Per David Anderson: yes—too much sodium or potassium without adequate water can damage kidneys and trigger imbalance the body has to correct. Always offer free water alongside supplementation, and follow label dosing rather than improvising.

Are paste electrolytes better than feed-through?

Per David Anderson: each fits different uses. Feed-through powder works for daily maintenance and consistent intake. Paste is better for pre-haul or pre-competition dosing where rapid absorption matters. Many performance barns use both at different times.
