Potassium Magnesium Sulfate - Feed Ingredient

Potassium magnesium sulfate, commonly known as Langbeinite, sulfate of potash magnesia (SOPM), or double sulfate of potassium and magnesium, is a naturally occurring mineral frequently used as a nutritional supplement and fertilizer. It contains potassium, magnesium, and sulfur in readily available sulfate forms. Potassium and magnesium are critical electrolytes that support cellular function, muscle contraction, nerve signaling, and metabolic processes in animals, including horses.

In equine diets, potassium magnesium sulfate may be incorporated primarily to address deficiencies or imbalances of potassium and magnesium, particularly in performance or working horses that lose significant electrolytes through sweat. Magnesium also plays a role in maintaining calm behavior and muscle relaxation.
