Buying Guide for the Best Horse Electrolytes

Now that you know the 10 best horse electrolytes options available on Amazon and Chewy. Here is an exclusive buying guide for you to help you figure out which one is suitable for your horse to feed.

Know Your Horses Exact Needs

Before buying any supplement for your horse, it is essential to know what kinds of supplementation your horse needs. For instance, does your horse have the correct level of fluids in its body cells? Or does your horse become dehydrated due to mineral deficiency?

For this reason, it’s always better to consult the vet of your horse for medical examination and tests, before buying any supplements. Doing this will help you decide which electrolyte supplements to choose for your horse because only a vet can tell you which ingredients to look for and which to avoid while shopping for horse electrolytes supplements.

Additionally, the vet will also let you know in case your horse is allergic to any ingredient so that you can avoid purchasing the one with that ingredient. Besides, it would help if you observe your horse’s behavior, any changes in coat and lung health, joint pain, and overall health. This will help the vet guide you more easily in finding the best type of supplement for your horse.

How Often Do You Need to Supplement Your Horse?

After deciding which type of electrolyte supplement is best for your horse, the next step is to determine how often your horse needs supplementation. For example, if the horse requires a supplement that offers vitamin C to boost the immune system, then should you feed your horse vitamin C tablets daily or once a week?

For that, you need to check your horse’s current vitamin C level, with the help of your vet. Additionally, your the blood test of your horse is required to know the exact amount of absorbed and digested nutrients in your horse’s body for active use.

Basically, these blood tests will let you know if your horses lack any specific nutrient, plus the severity of the deficiency can also be estimated. After that, you will be able to select the supplement that can help combat the deficiencies.

Determine if Your Horse Needs Combine Supplements

Should I give my horse combined supplements, or should I not? We know many horse owners have this question in their minds, especially if your horse has one or more deficiencies and other health issues.

Also, sometimes a product is designed to fulfill specific needs, such as to give relief from joint or bone pains, whereas you also need supplementation for your horse coat. If that is the case, then it’s best to combine supplements and make a custom treatment that meets your horse’s needs.

But if you are in doubt about the use of combined supplements, it is best to see your veterinarian, and both of you can work together to make a custom electrolyte supplement that will fulfill your horse’s needs.

Moreover, consulting a vet will save you from wasting your money on products that will not improve your horse’s health. Besides, taking expert advice on specific nutrients that your horse needs will also help you figure out how you can give those nutrients at home through supplementation.

People Also Asked

Let us quickly look at some of the most asked questions regarding horse electrolytes.

What are horse electrolyte supplements?

Horses need five main electrolytes including Potassium (K⁺), Chloride (Cl⁻), Sodium (Na⁺), Calcium (Ca²⁺), and Magnesium (Mg²⁺). All these electrolytes play a vital role in the horse’s body. And are required for almost all its body functions such as fluid balance and regulation of muscle contractions and such other important neurological functions.
Sodium is the primary electrolyte that plays a main role in regulating thirst. Sodium combines with chloride and forms sodium chloride, known as table salt.
The horse’s body loses electrolytes through feces, urine, and sweat. For instance, during exercise, horses sweat to cool down their bodies. This sweat contains five main electrolytes in different amounts.
Hence, the loss of electrolytes through excessive sweating causes loss of sodium and chloride in larger amounts, followed by calcium, magnesium, and potassium in lower quantities. The one way to compensate for this loss is to provide your horse with good-quality electrolytes to keep them healthy and hydrated.

Can you make horse electrolytes at home?

Yes, you can make horse electrolytes at home. Here is a palatable homemade horse electrolyte recipe.
Take table salt (NaCl) and Lo-Salt (KCl), both in a ratio of 2:1, to supply the 3 essential electrolytes. Remember you need to take similar sodium chloride and potassium concentrations as in sweat and make an isotonic solution.

Do horses need electrolytes in winter?

As electrolytes are essential to be fed to horses in hot summers, providing these supplements to your horses is vital in winters too. Because in winters, horses usually drink less water than they usually do, due to the cold outside. But even if your horse is not sweating or living in a warm place, or not sweating still, it can get dehydrated.

Can you overdose a horse on electrolytes?

You surely must have heard before “excess of everything is bad.” Similarly, too many electrolytes can be toxic to your horses. For instance, excess sodium can cause hypernatremia, a health condition that causes vomiting, dizziness, and diarrhea.
Similarly, too much potassium may cause hyperkalemia, a condition that affects kidney function in horses and cause nausea, irregular pulse, and heart arrhythmia. Also, the consumption of too many electrolytes may result in physical injuries like ulcers to mouth or stomach tissues.

Can I give my horses electrolytes daily?

Ideally, you should feed your horses the same amount of electrolyte daily. Providing your horse supplements just on competitions or tough workdays is not a good practice. Also, this will not help your horse get away with the deficiency over a long period of time.
One more thing, giving extra electrolytes won’t help your horse or improve their performance. Because their body can not store electrolytes, anything in excess is excreted.
Also, if you are giving your horse electrolytes for competition, then continue feeding for 2-3 days after the event for enhanced recovery. On the whole, you need to make sure that your horses have all the nutrients and minerals they require.


We hope our list of the best 10 electrolytes for horses will help you find the perfect supplement for your horse. Whereas reading our buying guide will give you a better understanding of your horse’s needs now and in the future.

Above all, you will make an informed decision about how they should be fed supplements (alone or in combination with others) when and how much should you feed them. Nevertheless, supplementation refills the essential electrolytes required by horses lost because of exercising and sweating.
