Magnesium

Magnesium is an essential mineral required for numerous physiological functions in horses. It plays a critical role in muscle contraction, nerve transmission, enzyme activity, and energy metabolism. As a macromineral, magnesium is necessary for maintaining normal neuromuscular function and supporting overall metabolic processes.

In equine nutrition, magnesium is commonly included in feed formulations and supplements to ensure adequate dietary intake. Deficiency in magnesium can lead to symptoms such as nervousness, muscle tremors, and poor coordination. While magnesium is naturally present in forages, supplementation may be necessary for horses with increased needs. Common supplemental sources include magnesium oxide, magnesium sulfate, and magnesium carbonate, each varying in bioavailability and digestibility

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