Horse Electrolytes Comparison Chart
A proper electrolyte balance and hydration should be main concerns of a horse owner. Electrolytes are required for fluid balance in cells. Electrolytes such as sodium (chemical symbol Na) and potassium (K) are essential for muscle function, which affects both skeletal muscles and the heart. Other electrolytes are responsible for other functions of the body.

Na= Sodium | K = Potassium | Ca = Calcium | Mg = Magnesium | Ph = Phosphorus
