What you need to know about giving your horse electrolytes


Electrolytes are minerals and salts dissolved in the horse’s body fluids. Having the proper balance and concentration of electrolytes in the body is essential for regulating hydration, blood pH and for nerve, muscle and heart function.


When horses sweat, significant amounts of electrolytes are lost, and must be replaced to maintain proper concentrations inside the body. During exercise horses can lose as much as 15-20 liters of body fluids through sweating.

Drinking water alone after exercise, without food or electrolyte supplementation, will dilute electrolyte concentrations inside the body. In response, the kidneys will eliminate the water (together with more electrolytes) in an effort to maintain the correct balance.


When supplementing with electrolytes it is important that your horse continues to drink a sufficient amount of water to maintain an appropriate balance of electrolytes in the body fluids. Concentrated electrolytes in the gut of a horse that is not†drinking will cause water to be drawn from the rest of the body into the stomach and intestines ? opposite to the direction you want it to flow.

A good electrolyte product should contain a proper balance of the electrolytes that are lost through sweating ? the primary ones being potassium, chloride, and calcium. It should also contain some form of glucose to aid in absorption from the gut.

Herbs for Horses ENDUROlytes formula contains these essential electrolytes†in the ideal ratio to replenish fluid loss in competitive horses, together with fructose and dextrose to aid the transport of the ions across the cell wall — helping to protect your horse form dehydration and electrolyte loss during the summer heat.
