The horse’s body is made up of a large number of cells, and these cells are more susceptible to damage and wear and tear than those of humans. As such, a horse’s electrolytes are constantly being flushed out of their body through sweat, urine, and exhaled air. We can help restore these electrolytes in the horse’s body through their feed or water supply, but it’s up to us to ensure the horse is consuming enough water to flush those electrolytes out.
This article will help you learn more about horse electrolyte supplements and help you select the best one for your horse’s needs.

Best Horse Electrolyte Supplements Buying Guide
Before choosing the best horse electrolyte supplement you should consider following options:
1. Water intake: Hydration is the most basic function of electrolyte supplementation. Horses often don’t drink enough plain water to meet their needs, so electrolytes are added to encourage consumption.
The electrolyte of most importance in horses is sodium, but other electrolytes also need to be replaced, including potassium, magnesium, and chloride.
The amount of electrolytes to supplement depends on the horse’s needs. A horse that sweats a lot, or has a high-energy job (such as a racehorse), needs more electrolytes than a horse that has a very sedentary job. A veterinarian can test the horse’s electrolyte levels and determine the exact amount to add.
2. Amount: The concentration of electrolytes in the water makes a big difference in uptake. Water with low concentrations may be almost imperceptible to horses, while water with high concentrations may cause them to reject it.
Water with a low concentration of electrolytes may be almost imperceptible to horses. Water with a high concentration may cause them to reject it.
‘We recommend 0.5 to 1.0 grams per liter for plain water, depending on the horse’s needs,’ says Dr. Forster. ‘For plain water, we recommend 0.5 to 1.0 g/L. For a drink with electrolytes, we recommend 1.5 to 3.0 g/L, depending on the electrolyte content and the horse’s needs.’
3. Time of day: Electrolytes are best absorbed when they’re added to water over a period of time, rather than all at once.
Horses tend to drink more during their regular times of water intake, so adding electrolytes to the water in the morning encourages them to drink more during a period when they’re likely to be well-hydrated.
4. Taste: If a horse won’t drink plain water with electrolytes added, then the concentration needs to be reduced. If a horse won’t drink plain water with no electrolytes added, then the electrolytes need to be added in a different form.
For example, instead of adding electrolytes to plain water, you can add them to a flavored drink such as Gatorade, which has its own flavor. You can also add them to molasses or grain water, or in some cases you can add them to a salt block.
5. Cost: Electrolyte supplementation can be very expensive if you use a premade electrolyte solution. ‘The most cost-effective way to add electrolytes is to use a plain water source and add the electrolytes yourself,’ says Dr. Forster.
6. Ease of administration: Some horses won’t drink plain water without electrolytes added, but they’ll drink it if it’s added to a flavored drink such as Gatorade.
‘Adding electrolytes to a flavored drink is the best way to encourage them to drink,’ says Dr. Forster. ‘In a study, a flavored drink was more attractive to horses than plain water with electrolytes added.’
