L-Lysine - Feed Ingredient

L-Lysine is an essential amino acid that plays a vital role in protein synthesis, tissue repair, and growth in horses. It is one of the key building blocks of proteins and is necessary for the production of enzymes, hormones, and antibodies. Since horses cannot synthesize L-Lysine on their own, it must be obtained through their diet.

In equine nutrition, L-Lysine is often included in feed formulations and supplements to ensure adequate levels of this essential amino acid. It is particularly important for growing horses, lactating mares, and performance horses, as it supports muscle development, immune function, and overall health. Adequate L-Lysine intake is crucial for optimizing the nutritional balance of equine diets and ensuring proper growth and maintenance.

The following equine feeds, supplements and products contain L-Lysine as an ingredient.
