Potassium Sulfate - Feed Ingredient

Potassium sulfate (K₂SO₄) is an inorganic salt composed of potassium and sulfate ions. It is commonly used as a source of potassium in animal feed formulations. Potassium is an essential macromineral that plays a crucial role in nerve function, muscle contraction, and osmotic balance in horses.

In equine nutrition, potassium sulfate serves as an alternative potassium source to potassium chloride, particularly in cases where chloride intake needs to be controlled. It is often included in electrolyte supplements to help maintain hydration and electrolyte balance, especially for horses in heavy training or those exposed to hot climates. While potassium is naturally abundant in forage-based diets, supplementation may be necessary for horses with increased losses due to sweating.

The following equine feeds, supplements and products contain Potassium Sulfate as an ingredient.
