Calcium Sulfate - Feed Ingredient

Calcium sulfate (CaSO₄) is a mineral compound commonly used as a dietary supplement in animal nutrition, including equine diets. It serves as a source of calcium and sulfur, two essential minerals that contribute to bone strength, metabolic functions, and overall health. Calcium plays a crucial role in muscle contraction, nerve function, and skeletal integrity, while sulfur supports joint health, amino acid synthesis, and the production of connective tissues.

In horse diets, calcium sulfate is often included in mineral supplements or feed formulations to help balance the calcium-to-phosphorus ratio, which is vital for proper bone development and maintenance, or to increase the sulfur levels in the diet.

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