L-Histidine - Feed Ingredient

L-Histidine is an essential amino acid, meaning it must be supplied through the diet as horses cannot synthesize it in sufficient amounts internally. It is a precursor for several important biological compounds, including histamine and carnosine, and plays a role in enzyme activity, protein synthesis, and hemoglobin function.

In equine nutrition, L-Histidine is considered particularly relevant for young, growing horses and for those undergoing intense training, where demands for muscle protein synthesis are increased. It may also influence the availability of other amino acids by modulating absorption and transport processes. As a feed ingredient, L-Histidine is typically included as part of a balanced amino acid profile in protein supplements or premixes. It can be synthetically produced through microbial fermentation and then purified for use in animal feeds.
