Marshmallow Root - Feed Ingredient

Marshmallow root is derived from the root of the Althaea officinalis plant, a perennial herb native to Europe and Western Asia. The root contains high levels of mucilage, a gel-like polysaccharide that becomes viscous when mixed with water. This mucilaginous property underlies its primary use in equine supplements focused on digestive or respiratory support.

In equine nutrition, marshmallow root is typically used in powdered or dried form as part of herbal blends. It is valued for its demulcent action, which can provide a soothing coating to mucous membranes in the gastrointestinal tract. This physical effect may help support horses with sensitive digestive systems or during periods of dietary stress. Its use in respiratory supplements is based on similar mucilage-driven properties that may soothe irritated airways.

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