L-Methionine - Feed Ingredient

L-Methionine is an essential amino acid, meaning it cannot be synthesized by the horse’s body and must be supplied through the diet. It contains sulfur and serves as a building block for protein synthesis. In equine feeds and supplements, L-Methionine is typically included to help meet amino acid requirements, especially in diets where the natural protein sources may be limited or unbalanced in amino acid profile.

This amino acid plays a key role in the synthesis of other sulfur-containing compounds such as cysteine and taurine, as well as in methylation reactions critical to cellular function. L-Methionine is often used in formulations for growing horses, broodmares, and performance horses where protein and amino acid needs are elevated. It may also be present in hoof supplements, as methionine contributes to keratin production. Since it is added in purified form, L-Methionine provides a precise and highly bioavailable source of this nutrient in equine diets.
