Ingredient
Magnesium Sulfate
Magnesium sulfate (MgSO₄) is an inorganic compound composed of magnesium, sulfur, and oxygen. It is commonly available in hydrated forms, such as magnesium sulfate heptahydrate (Epsom salt). This compound is used in animal nutrition as a supplemental source of magnesium and sulfur, both of which play essential roles in physiological functions.
In equine nutrition, magnesium sulfate is included in feed formulations or supplements to support magnesium balance in the diet. Magnesium is critical for muscle function, nerve signaling, and enzyme activity. However, excessive supplementation should be avoided, as high doses of magnesium sulfate can have a laxative effect.
The following equine feeds, supplements and products contain Magnesium Sulfate as an ingredient.
