The most important electrolytes for horses are:
- Sodium (Na): Ensures a good fluid balance and supports the absorption of other electrolytes.
- Potassium (K): Essential for muscle and nerve function.`
- Chloride (Cl): Works with sodium to maintain fluid balance.
- Calcium (Ca): Important for muscle contraction, bone health and enzyme activity.
- Magnesium (Mg): Plays a role in muscle relaxation and energy production.
When horses sweat, they lose sodium, chloride and potassium in particular, which is why these need to be replenished most often.
