This product is a pure, concentrated powder form of dl-methionine, an essential amino acid that serves as a building block of protein in the equine diet. It is intended for horse owners looking to top-dress a daily feed ration with additional sulfur-containing amino acids. Methionine is a component of collagen, so the supplement is formulated to support the normal structure and function of hair, coat, skin and hooves, along with normal liver function and urinary pH. Each container holds powder that is simply measured and mixed into the horse's regular feed once a day. No mixing equipment or preparation is required beyond a standard feed scoop or measuring spoon. The tub should be kept sealed between uses to protect the powder from moisture.
