Sodium Selenite

Sodium selenite is an inorganic form of selenium, a trace mineral that is essential for various physiological functions in horses. Selenium plays a crucial role in antioxidant defense, thyroid hormone metabolism, and immune function. Sodium selenite is commonly used as a feed supplement to ensure adequate selenium intake in equine diets.

In equine nutrition, sodium selenite is often included in feed formulations and supplements to prevent selenium deficiency, which can lead to muscle disorders, impaired immune function, and reproductive issues. It is important to provide the appropriate amount of sodium selenite, as both deficiency and excess selenium can be harmful to horses. Selenium supplementation should be carefully managed to maintain optimal health and performance.

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