Equistro Electrolyt 7 for replenishing electrolytes after heavy exertions. Horses with a very active lifestyle who sweat a lot lose electrolytes. The faster replenishing of electrolytes with Elektrolyt 7 allows the horse to physically recover faster. Electrolytes are mineral salts that are essential to many bodily functions. If the electrolyte balance is disrupted, for example after illnesses or heavy exertions (sweating), it requires an extra supply of electrolytes. A shortage can cause cramps or exhaustion. Equistro Electrolyt 7 is an animal feed supplement that can be mixed in both the horse's water and its feed.
