Methionine - Feed Ingredient

Methionine is a sulfur-containing essential amino acid that plays a crucial role in protein synthesis, metabolism, and various physiological functions in horses. As an essential amino acid, it must be obtained from the diet since horses cannot synthesize it internally.

In equine nutrition, methionine serves as a precursor for other sulfur-containing compounds, such as cysteine and taurine, which are important for tissue repair, antioxidant function, and keratin formation. It is particularly relevant in hoof health due to its role in keratin synthesis, the primary structural protein in hooves and hair. While methionine is naturally present in forages and protein-rich feeds, supplementation may be necessary in diets that are low in high-quality protein sources.

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