Glycine - Feed Ingredient

Glycine is a non-essential amino acid that plays a role in protein synthesis, collagen formation, and various metabolic processes. It is the simplest amino acid in structure and is naturally found in proteins, particularly in connective tissues such as collagen and gelatin. While horses can synthesize glycine endogenously, it is also obtained through dietary protein sources such as alfalfa, soybean meal, and other high-protein feed ingredients.

In equine nutrition, glycine contributes to muscle function, tissue repair, and the synthesis of important compounds such as creatine, glutathione, and heme. It also acts as a neurotransmitter with both excitatory and inhibitory functions in the central nervous system. Glycine is sometimes included in feed formulations and supplements, particularly those aimed at supporting joint health or digestive function, as it is a key component of collagen and gastric mucus.

Since glycine is classified as a non-essential amino acid, dietary deficiencies are unlikely under normal feeding conditions.

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